* In the fuel tank: This is the most common location for this model year. If this is the case, you won't be able to access it without dropping the fuel tank.
* On the frame rail: Less common, but possible. This would require looking along the frame rails near the fuel tank.
To find it definitively:
1. Consult your owner's manual: This is the best place to start. It should have a diagram showing the location.
2. Check online repair manuals: Sites like Chilton's or Haynes provide detailed diagrams and instructions specific to your engine. You'll need to know your specific engine size (e.g., 3.7L, 4.7L, 5.7L).
3. Search online for your specific year, make, model, and engine: A search like "2004 Dodge Ram 1500 4.7L fuel filter location" will often yield relevant images and forum posts from other owners.
Because of the potential difficulty in accessing the filter (particularly if it's in-tank), it's often recommended that a professional mechanic handle fuel filter replacement on this vehicle.
