* For most gasoline engines: The fuel filter is typically located on the frame rail, somewhere near the fuel tank, often towards the rear of the vehicle. It's usually a cylindrical canister. You'll likely need to get under the truck to access it.
* For diesel engines: The location can vary slightly even within diesel models. It's generally still under the truck near the fuel tank, but possibly more towards the center of the vehicle. Again, access requires getting under the truck.
To find it definitively:
1. Consult your owner's manual: This is the most reliable source. The manual will have diagrams showing the location of the fuel filter and other components.
2. Use a repair manual: A repair manual (like a Chilton's or Haynes) specific to your year, make, and model will provide detailed information and diagrams.
3. Search online forums: Websites and forums dedicated to Dodge Ram trucks often have discussions and pictures showing the fuel filter location for specific engine types. Be sure to specify your engine size (e.g., 4.7L, 5.7L Hemi, Cummins diesel) in your search.
Important Note: Working with fuel lines and filters involves potential fire hazards. If you're not comfortable performing this task yourself, take it to a qualified mechanic.
