To locate it definitively:
* Consult your owner's manual: This is the best place to start. The manual should have a diagram showing the fuel system.
* Use a repair manual: A Haynes or Chilton repair manual for your specific year and model Bronco will have detailed diagrams and instructions.
* Look for a cylindrical canister: The fuel filter is usually a cylindrical canister with fuel lines connected to it.
* Trace the fuel lines: Start at the fuel tank and follow the fuel lines forward. The filter will be somewhere along that line.
Be aware that working with fuel lines requires caution. Avoid sparks, and if you're uncomfortable, have a qualified mechanic do the work for you.
