F-150 Fuel Filter Replacement

How to Replace the Fuel Filter on a Ford F-150


Gasoline straight from the pump is dirty, and over time debri will build up in the fuel tank. The fuel filter protects your engine from these harmful particulates. The downsides is that it needs to be replaced regularly; both performance and fuel economy will suffer should the fuel filter becomes clogged. Change the fuel filter every 10,000 miles or at least once per year. It's an inexpensive way to maximize fuel economy and changing the filter should take less than 15 minutes once you know how its done. Wear safety glasses when changing the fuel filter - gasoline in the eyes is painful and dangerous, and there's no way of avoiding leaking fuel once the filter is removed.

• You're going to need a fuel filter wrench in order to remove the old filter. The tool is inexpensive, and any auto parts store should carry one.

• The fuel filter is located on the driver side inner frame rails and looks like a small metal canister (see photo). If you have trouble locating it, simply follow the fuel lines from the tank.

• Begin by disconnecting the retaining clips from the fuel filter. This is accomplished by first pushing the top of the clip down, and then sliding the clip forward and out of the fuel line connection (see photo).

• With the retaining clips removed, insert your fuel filter wrench into the fuel line connection by opening the tool, sliding it over the nipple of the fuel filter, and closing it.
• With the fuel filter wrench secured on the fuel filter, slide the wrench into the fuel line connector (mild force required) while pulling the fuel line connector away from the fuel filter. When performed correctly, the fuel line will seperate from the filter (it may take a few tries to get the hang of it).

• Repeat on opposite side of fuel filter so that both lines are removed, and then remove the fuel filter from its clip.

• To install your replacement fuel filter, you do not need the fuel filter wrench.

• Install the new filter into the clip that holds it in place. Be sure to install the new filter in the correct direction so that the flow direction is correct. If the direction is not stamped on the filter, install it in the same manner the previous was removed.

• Connect the fuel lines to the new fuel filter. Double check that they locked and are secure.

• Reconnect the fuel line retainer clips reverse how they were removed.
