* For gasoline engines (4.7L, 5.7L Hemi): The fuel filter is typically located on the frame rail, near the fuel tank, but often hidden and difficult to access. You'll likely need to look underneath the truck. It's usually mounted vertically.
* For diesel engines (5.9L Cummins): The fuel filter is usually located on the engine itself, more readily accessible than on gasoline models. Consult a repair manual or online diagram specific to the 5.9L Cummins engine in your truck.
To find the exact location:
1. Consult your owner's manual: This is the best place to start. It will have diagrams and descriptions.
2. Use an online repair manual: Sites like Chilton or Haynes offer detailed repair manuals specific to your year and model. They will have diagrams showing the fuel filter location.
3. Search online: A Google image search for "[your engine type] 2004 Dodge Ram fuel filter location" might show pictures of the filter's location on similar trucks.
Caution: Fuel is flammable and under pressure. Always take appropriate safety precautions when working near fuel lines and components. If you're not comfortable working on your vehicle yourself, take it to a qualified mechanic.
