1. Identify your engine: Look for an engine code stamped on a metal plate near the engine or in the owner's manual. Knowing the engine type (e.g., 302 V8, 351 V8, 360 V8, inline 6) is crucial.
2. Check common locations: Once you know the engine, these are common spots for the fuel filter on a '76 F-100:
* Frame rail near the fuel tank: This is a frequent location. Look along the frame rail, near the fuel tank, for a cylindrical canister that might have fuel lines connected to it.
* In the engine compartment: Less common, but possible, especially on some engine configurations. Look closely around the fuel pump and carb (if it's a carburetor engine).
* Consult a repair manual: A repair manual specific to your truck's year and engine will have diagrams showing the precise location of the fuel filter. This is the most reliable method. You can find these online or at auto parts stores.
Without knowing the engine type, providing a definitive answer is impossible. Always exercise caution when working near fuel lines and components.
