Appellant, Director of the United States Customs Service (“Customs Service”), appeals the district court’s order compelling the Customs Service to return claimant/ap-pellee’s car, seized pursuant to 19 U.S.C. § 1595 as property used to aid the introduction of illegal drugs into the United States. Appellant contests the district court’s findings that (1) the United States had insufficient cause to seize claimant’s automobile, and (2) claimant’s due process rights were violated when an unreasonable delay ensued between seizure and a post seizure hearing. We hold that the district court erred in ordering the government to return claimant’s car because (1) the government did demonstrate sufficient probable cause to warrant seizure, and (2) there was no undue delay between seizure and hearing under the test defined in
United States v. $8850,
I. Statement of Facts and Course of Proceedings
On December 30, 1991, the Customs Service seized appellee Ruby Nnadi’s (“Nna-di”) black Nissan Pulsar (“Pulsar”) from the parking lot of an apartment complex in Austеll, Georgia. The vehicle was seized pursuant to 19 U.S.C. § 1595a, which provides for forfeiture of property used to aid in introducing any item into the United *685 States contrary to law. 1 Nnadi was present during the seizure and aware that the Customs Service was confiscating her car.
The Customs Service based its seizure on information obtained from Jestine Joyner (“Joyner”) who had been convicted of attempting to smuggle 5.5 pounds of heroin into the United States from the Philippines. Joyner told Special Agent James R. Wiggins that on June 23 or 24, 1991, Nnadi had used the Pulsar to drive Joyner to the Atlanta airport to catch a flight to the Philippines. Nnadi knew that Joyner’s mission entailed obtaining heroin and smuggling it back into the United States. Indeed, Nnadi anticipated splitting the profits from this endeavor with Joyner. In addition to Joyner’s testimony, the government found (1) information in Joyner’s possession linking Nnadi to the heroin venture, and (2) independent information linking Nnadi to a broader smuggling conspiracy.
Following the seizure, the government initiated administrative forfeiture proceedings against the Pulsar pursuant to 19 U.S.C. § 1607 which requires that notice of forfeiture be sent to any party having an interest in a seized article. Such notice was mailed on January 16, 1992, but was addressed to the wrong apartment number. The notice included an explanation of administrative forfeiture proceedings and information on how to challenge the forfeiture by filing a claim and a cost bond. Nnadi claims she never received this notice.
On February 10, 1992, Nnadi filеd a complaint in the U.S. District Court for the Northern District of Georgia for return of the Pulsar. Simultaneously, she filed a motion for “Temporary Restraining Order, Preliminary Injunction, and Consolidation of Hearing with Trial on the Merits.” Following a hearing on February 19, 1992, the district court ruled that the Pulsar had been seized in violation of due.process because (1) the vehicle was seized without probable cause, and (2) at the time of the district court’s ruling there had not yet been a post-seizure hearing at whiсh Nnadi could have challenged the seizure (“the Order”). Consequently, the district court ordered the defendant Customs Service to return the Pulsar and enjoined the defendant from re-seizing the vehicle “until and unless the plaintiff is given an opportunity to challenge the defendant’s legal basis for forfeiture under 19 U.S.C. § 1595a and defendant has established probable cause for the seizure.”
On March 4, the Customs Service filed a notice of appeal of the Order together with a motion for a stay pending disposition on appeal. The district court ordered a stay through April 10, 1992. On April 10, the government filed an emergency motion with this court for stay pending appeal. This court granted the stay.
On March 6, Nnadi finally addressed the administrative forfeiture proceeding by filing a Claim and Declaration in Support of Request for Waiver of Bond. In late April 1992, the Customs Service, pursuant to 19 U.S.C. § 1603, asked the United States attorney to institute a judicial action against the Pulsar. In response, thе United States attorney filed a complaint for forfeiture with the U.S. District Court for the Northern District of Georgia claiming that the United States had sufficient probable cause to obtain forfeiture under 21 U.S.C. § 881(a)(4) and 19 U.S.C. § 1595a. 2 This action is still pending before the district court.
II. Discussion
The district court erred on several grounds when it ordered the defendant to *686 return the Pulsar to Nnadi. First, the court erroneously determined that the government did not have probable cause to seize the Pulsar. Second, it incorrectly applied the Supreme Court’s test fоr determining the reasonableness of a delay between seizure of a forfeitable vehicle and a final determination concerning whether the seized vehicle should be returned to the owner. Third, the court failed to apply the traditional four-prong test for determining when a preliminary injunction should be granted.
A. Probable Cause
The United States bears the same burden of proving probable cause in civil forfeiture actions brought under the customs laws as it does in civil forfeiture actiоns brought under the provisions of 21 U.S.C. § 881. 19 U.S.C. § 1615. Therefore, case law developed in cases under section 881, providing for forfeiture of property used to facilitate drug trafficking, applies to forfeitures under 19 U.S.C. § 1595a as well. In both circumstances, the United States must demonstrate that it had probable cause to seize the property. 19 U.S.C. § 1615. Section 1615, entitled “Burden of proof in forfeiture proceedings” provides that:
In all suits or actions [other than those involving fraud, gross negligence оr negligence] brought for the forfeiture of any vessel, vehicle, aircraft, merchandise, or baggage seized under the provisions of any law relating to the collection of duties on imports or tonnage ... probable cause shall be first shown for the institution of such suit or action, to be judged by the court.

See also United States v. One 1975 Ford Pickup Truck, Etc.,
Probable cause exists when the United States has reasonable grounds to believe that there is a substantiаl connection between the property charged and specific transactions involving illicit drugs.
United States v. $41,305 in Currency & Traveler’s Checks,
Hearsay statements are admissible to support the existence of probable cause.
United States v. One Parcel of Real Estate,
These statements аlone amounted to probable cause because they provided a “reasonable ground for a belief of guilt, supported by less than prima facie proof but more than mere suspicion” that the Pulsar “was used to facilitate the transportation, concealment, or possession” of illegal drugs.
One 1979 Porsche,
The above information proves that the government had probable cause to believe that a substantial connection existed between the Pulsar and the heroin that Joyner had attempted to smuggle into the United States.

B. The Four-Prong Test for Unreasonable Delay
The Supreme Court has set forth a four-part test for determining whether an unreasonable delay has transpired between seizure of forfeitable property and a final hearing concerning the ultimate dispositiоn of the property seized.
United States v. $8,850 in United States Currency,
1. Unreasonableness of Delay and Reasons for Delay
The district court held that an undue delay had transpired between the government’s seizure of the Pulsar and a hearing to determine the ultimate disposition of the seized propеrty. The court’s ruling was based on the forty days that had elapsed between the date the Pulsar was seized and the date the court addressed Nnadi’s claim. The court’s rulings ignored (1) the government’s diligence in abiding by the procedures relating to forfeiture and subsequent judicial hearings set forth in 19 U.S.C. §§ 1603, 1604 and 1607 and the fact that a prompt hearing would have ensued if Nnadi had filed a claim with the Customs Service contesting the government’s seizure and (2) the relatively short delay which forty days represents under thе circumstances.
The customs statutes oblige the government to send written notice to any party having an interest in a seized article as long as applicable procedures explaining how to contest the seizure. 19 U.S.C. *688 § 1607. Under section 1603(b), the Customs Service must “report promptly” any seizure to the United States attorney whenever legal proceedings are necessary. 19 U.S.C. § 1603(b). 3 Such proceedings would be necessary whenever an individual contests a Customs Servicе seizure. Under section 1604, the United States attorney to whom the matter has been referred is obligated “forthwith to cause the proper proceedings to be commenced and prosecuted, without delay ” before the appropriate district court. 19 U.S.C. § 1604 (emphasis added).
In this case, the Customs Service sent Nnadi the mandated written notice along with an explanation of how to challenge the forfeiture by filing a claim and a cost bond. Apparently, the notice wаs addressed to the wrong apartment number and Nnadi claims she never received it. Nevertheless, the government has proffered signed affidavits indicating that Nnadi and her lawyer were not only aware of the forfeiture (Nna-di witnessed the seizure), but that Nnadi’s lawyer actually contacted the Customs Service office on January 13, 1992 and January 16, 1992, concerning the forfeiture. 4
In this case, the delay between the forfeiture and a post-seizure hearing was justified by the government’s involvement with the active administrative forfeiture proceedings involving the Pulsar.
$8850,
The district court also stated that an unreasonable delay of six months separated commission of the alleged drug related conduct (driving Joyner to the airport) and the seizure. This determination by the district court misses the essence of the concept of unreasonable delay in forfeiture cases. Due process is violated when a claimant is deprived of her property for an unreasonable amount of time prior to a hearing on the merits, $8850, supra, not when there is a delay which postpones the seizure of the property.
In addition, the period between the acquisition of probable cause information and seizure is far from unreasonable. Although the Joyner importation incident occurred in late June 1991, thе government
*689
did not learn of Nnadi’s involvement until December 12, 1991, less than three weeks prior to seizure. Thus, this information did not reach the appropriate special agent until December 19, eleven days prior to seizure. This minor delay is not unreasonable because “[b]oth the Government and the claimant have an interest in a rule that allows the Government some time to investigate.”
$8850,
2.Nnadi’s Assertion of Her Rights
The third factor in the
$8850
balancing test requires that claimant show that she diligently asserted her rights to a prompt рost-seizure hearing. Nnadi has made no such showing, and in fact has shown that she willfully avoided the appropriate channels. If Nnadi had filed the appropriate claim with the Customs Service, the customs officer would have been obligated under section 1603(b) to refer the matter to the United States attorney. Section 1604 then obligates the United States attorney to “cause the proper proceedings to be commenced and prosecuted” in the appropriate district court. 19 U.S.C. § 1604. In addition, a claimant may speed up civil forfeiture proceedings by (1) filing an equitable claim seeking an order compelling the filing of the forfeiture action or return of the seized property, or (2) requesting that the Customs Service refer the matter to the United States attorney.
$8850,
3.Prejudice to Defendant
Finally, a delay may be unreasonable if the defendant has been overly prejudiced by the delay between seizure and hearings. “The primary inquiry here is whether the delay has hampered the claimant in presenting a defense on the merits, through, for example, the loss of witnesses or other important evidence.”
United States v. $8850,
4.Balance of Von Neumann Factors
The Von Neumann factors weigh heavily in favor of a finding that no unreasonable delay transpired between seizure and post-seizure hearings and that the district court erred when it held otherwise. Nnadi was aware of the forfeiture by customs agents, as was her lawyer, and chose to initiate this action rather than file a claim through thе correct channel. In addition, even if she had been unaware of the administrative proceeding when she filed this action on February 10, 1992, she certainly became aware of such when the government’s responded to her complaint on February 18. 6 At that time, a mere forty *690 days after forfeiture, she could have exercised her rights to compel a speedy civil forfeiture action.
Nnadi ignored the two appropriate courses of actions and instead initiated this case fоr return of the Pulsar. She has been denied a timely post-seizure trial solely because she attempted to circumvent the prescribed procedure for dealing with seized property. Currently, there is an appropriate forfeiture proceeding pending before the district court in which she can vindicate her rights if she proves that she has been unjustly denied her property. Because Nnadi failed to avail herself of her rights and because of the relatively shоrt time period involved, we hold that the district court erred when it concluded that Nnadi had been denied her due process rights by an “unreasonable” delay between seizure and hearing.
C. Preliminary Injunction
The district court not only erred in its findings on the issues of probable cause and unreasonable delay, but it made a broader, procedural error by not applying the traditional test associated with the grant of a preliminary injunction. Case law required the district court to make four findings in favor оf Nnadi before granting the injunction: (1) a substantial likelihood that Nnadi would succeed on the merits of a civil forfeiture hearing; (2) a substantial threat that she would suffer irreparable injury if the injunction were not granted; (3) the threatened injury to the Nnadi outweighs the harm an injunction may cause the government; and (4) a grant of preliminary injunction would not disserve the public interest.
West Point-Pepperell, Inc. v. Donovan,
We review a district court’s grant of a preliminary injunction under an abuse of discretion standard. The court’s discretion, however, is not unbridled. A court must exercise its discretion in light of the four prerequisites for the “extraordinary relief” of preliminary injunction.
West Point-Pepperell,
The district court failed to apply, or even mention, this four-part test before granting Nnadi’s motion for preliminary injunction. We cannot credit the district court with an implicit application of the preliminary injunction test because the claimant clearly did not prove the four necessary components as required by Canal Authority. In particular, the discussion in parts II.A and II.B, supra, shows that Nnadi failed to demonstrate that she had a substantial likelihood of success on either of her claims: (1) that the government failed to prove probable cause, and (2) that an undue delay transpired between seizure and a post-seizure hearing on the merits. 7
Nnadi bore the burden of proving all four preliminary injunction factors, Canal Authority, supra. Consequently, we need not discuss whether she has proven the other three factоrs. Because Nnadi failed to demonstrate a substantial likelihood that she would succeed on the merits, the district court abused its discretion in granting *691 Nnadi’s preliminary injunction and in ordering the government to return her car.
III. Conclusion
For the above reasons we REVERSE the district court and VACATE the order requiring the government to return the Pulsar pending an adequate post-seizure hearing.
Notes
. Section 1595a provides for forfeiture of: every vessel, vehicle, animal, aircraft or other thing used in, to aid in, or to facilitate, by obtaining information or in any other way, the importation, bringing in, unloading, landing, removal, concealing, harboring, or subsequent transportation of'any article which is being or has been introduced, or attempted to be introduced, into the United States contrary to law.
. Section 881(a) provides for forfeiture of all:
aircraft, vehicles, or vessels, which are used, or are intended for use, to transport, or in any manner to facilitate the transportation, sale, receipt, possession, or conceаlment of [controlled substances obtained in violation of the drug laws].
. Section 1603(b) provides:
Whenever a seizure of merchandise for violation of the customs laws is made ... and legal proceedings by the United States attorney in connection with such seizure ... [is] required, it shall be the duty of the appropriate customs officer to report promptly such seizure ... to the United States attorney for the district in which ... such seizure was made_
. In any case, at the time Nnadi filed her complaint in district court, shе had only been subject to forty days of seizure. Under relevant case law, much longer times than this have been held to be not excessive. In
$8850,
the Court held that an eighteen month gap between seizure and a civil forfeiture hearing was not excessive.
Id.
.The fact that Nnadi and her lawyer must have known that the government was awaiting a filing of an administrative claim is bolstered by (l) her lawyer's phone calls to the customs office concerning the seizure and (2) the actual filing of such claim on March 6. Nnadi states in her Response to [the Government’s] Motion to Supplement Record on Appeal that she "wanted to have the claim handled judicially, rather than through administrative forfeiture proceedings” but that she was filing under protest to guard against a possible procedural bar from a failure to file by a particular date. Clearly, Nnadi knew of the section 1603 and 1604 procedure but preferred to create her own timing, remedy and forum.
. The government’s response to claimant’s Motion for Temporary Restraining Order, Preliminary Injunction and Consolidation of Hearing with Trial on the Merits states, in part:
On December 31, 1991, a Seizure Report prepared under the supervision of Special Agent Wiggins was approved by his supervisor and transmitted to the District Director of the U.S. Customs Service. Shortly thereafter, the Fines, Penalties and Forfeiture Officer in the District Director’s Office received the Seizure Report and instituted administrative forfeiture *690 proceedings under 19 U.S.C. § 1607 and 19 U.S.C. § 162.31.
. At a hearing on the merits, the government would again bear the initial burden of proving probable cause.
