Items you will need

  • Quick-disconnect tool

  • Socket set

  • Socket wrench

  • Masking tape (optional)

  • New fuel filter

Replacing the fuel filter every 30,000 miles ensures the fuel system in the Ford E-150 stays free and clear of debris and sediments. The fuel tank contains contaminants that gets past the strainer built onto the fuel pump. The filter will then remove these sediments and ensure the fuel flows to the engine non-polluted. The filter is accessible from under the van and it takes minimal time to access it.

Ensure the van is parked on a flat, level surface. Set the parking brake to ensure the van does not roll.

Open the hood to access the engine compartment. Locate the fuse panel near the battery. Open the panel and pull the fuel pump relay. It will be labeled for easy access.

Start the van to allow it to depressurize the fuel system. Once the van stalls, the pressure is released in the fuel lines. Remove the keys from the ignition. Re-install the relay once the van stalls out.

Find the fuel filter underneath the van. Trace out the fuel lines to the driver's door. The filter is located along the frame rail.

Place the quick-disconnect tool over the inlet fitting and pull toward the filter. This will release the line from the filter. Mark the inlet line with a piece of masking tape. Pull the outlet line off the filter with the quick-disconnect tool.

Slide the filter off the mounting bracket by loosening the retaining bolt with a socket wrench. Slide the filter away from the bracket.

Mount the new filter to the bracket. Tighten the bracket with a socket wrench. The arrow on the filter needs to be pointing toward the front of the van, as it designates the direction of fuel flow.

Remove the masking tape from the inlet line and push it onto the fuel filter. The line will lock in place once it is pushed far enough onto the filter. Repeat to install the outlet line.

Start the van and allow it to idle for five minutes. Observe for leaks around the fuel filter.


The van may not start right away, as the fuel pump needs to be primed. Prime the pump by turning the ignition key to the "start" position and allowing the pump to run for five seconds. Turn the key once the pump is primed and the van will start.


Use caution when working around gasoline as it is very toxic and flammable.
