To be sure, I recommend:
* Checking your owner's manual: This is the best source for the precise location on your particular truck.
* Looking at a repair manual specific to your 1994 F-150: A Haynes or Chilton manual will have diagrams and instructions.
* Searching online for "1994 Ford F-150 fuel filter location" along with your engine size (e.g., 4.9L, 5.0L, 5.8L): This will bring up images and potentially videos showing the location on similar trucks.
Always exercise caution when working near fuel lines and components. Wear safety glasses and gloves, and make sure the area is well-ventilated. If you are uncomfortable performing this task yourself, take your truck to a qualified mechanic.
