* On the frame rail: This is a common location for many 1994 Dodge Ram trucks. Look along the frame rail, near the fuel tank, for a cylindrical canister.
* In the engine compartment: Less common, but possible, especially if it's a different engine configuration.
To find it definitively:
1. Consult your owner's manual: This is the best source. It will show you a diagram of your specific truck's fuel system.
2. Look for fuel lines: Follow the fuel lines from the fuel tank towards the engine. The filter will be inline on one of those lines.
3. Use a repair manual: A Haynes or Chilton repair manual for your specific year, model, and engine will have diagrams and instructions.
4. Search online: Search for "1994 Dodge Ram 4x4 fuel filter location [your engine size]" (e.g., "1994 Dodge Ram 4x4 fuel filter location 5.2L"). Images from other owners might help you pinpoint it.
Be careful when working near fuel lines – fuel is flammable. If you're not comfortable working on your own vehicle, take it to a mechanic.
