To be absolutely certain, I strongly recommend:
* Consulting your owner's manual: This is the best source of information for your specific vehicle.
* Using a repair manual specific to your year and model: These manuals provide detailed diagrams and instructions.
* Searching online for images: Search for "2000 Dodge Ram Van 3500 fuel filter location" on Google Images or YouTube. You'll likely find photos or videos showing the location on a similar van.
Remember to be careful when working around fuel systems. Fuel is flammable and working on the fuel system requires proper safety precautions.
