It's not reliably in a single, standard location. It could be:
* In the fuel tank: This is the most common location for in-tank fuel pumps. You'll need to access the fuel tank to find it. This typically involves dropping the tank (a major job), or sometimes there's access from underneath.
* On the frame rail: Some older vehicles placed the fuel pump externally on the frame rail, near the tank.
* In the engine compartment: Less common, but possible, particularly with older designs or modifications.
To find it, you will need to:
1. Identify your RV's chassis and engine: Look for information on a sticker or plate usually found inside the driver's side door jamb, or in the engine compartment. This information (like chassis type and engine size) is crucial.
2. Consult a repair manual: A repair manual specific to your RV's chassis and engine will give you the precise location of the fuel pump. You can find these online or at auto parts stores.
3. Search online forums: Search online forums dedicated to Ford RVs or your specific RV model. Someone may have already asked and answered this question. Include the chassis and engine details in your search.
4. Look for fuel lines: Follow the fuel lines from the fuel tank. They'll lead you to the fuel pump. Be cautious, fuel lines can be under pressure. Be careful working around fuel.
Warning: Working with fuel systems is potentially dangerous. If you're not comfortable working on your RV's fuel system, take it to a qualified mechanic.
