* Junkyards/Salvage Yards: This is often the most cost-effective option. Search online for auto salvage yards in your area or those that ship nationwide. Specify the year, make, model, and engine size of your van. Be sure to check their inventory or call them directly.
* Online Parts Retailers: Websites like RockAuto, Car-Part.com (which searches junkyards), and eBay are good places to start. You'll likely need to use your van's VIN number to ensure compatibility. Be prepared for potentially higher prices than a junkyard.
* Dodge Dealerships: They can order the part for you directly from Mopar (Dodge's parts division), but expect to pay the highest price. This is only a worthwhile option if you can't find it elsewhere.
* Local Auto Parts Stores: While less likely to have this specific part in stock, they might be able to order it for you, potentially from a larger warehouse or distributor.
Important Considerations:
* Year: The year of your Dodge Ram Van 3500 is crucial. Parts changed across model years.
* VIN: Using your Vehicle Identification Number (VIN) is the most accurate way to ensure part compatibility.
* Condition: If buying used, carefully inspect the fuel filler neck for damage, rust, and proper sealing before purchase. A damaged filler neck can lead to fuel leaks and safety hazards.
Start with the junkyards and online parts retailers. If those fail, then consider the dealership as a last resort. Remember to compare prices and shipping costs before making a purchase.
