However, the most common location is on the frame rail, near the fuel tank. You'll likely find it as a cylindrical canister with fuel lines connected to it. It might be secured with a clamp or straps.
To be absolutely sure, I recommend:
* Checking your owner's manual: If you have the original owner's manual, it will have a diagram showing the location of the fuel filter.
* Consulting a Ford Bronco repair manual: These manuals provide detailed diagrams and instructions for your specific year and engine. Haynes and Chilton are popular brands.
* Visually inspecting the fuel lines: Start at the fuel tank and follow the fuel lines towards the carburetor. The filter will be somewhere along that route.
Be careful when inspecting the fuel system; fuel is flammable. If you are not comfortable working on your vehicle's fuel system, it's best to take it to a qualified mechanic.
