How To Replace The Fuel Filter In Your Ford F150
With proper maintenance, good driving habits, and a little luck, your Ford F150 should last for years (if not decades). Still, it may be a bit daunting to work on. Ask anyone who’s had to climb inside the hood of one of them. But that shouldn’t deter you! Just working on your truck and getting the most out of it is half the fun.
Today’s post is about how to replace the fuel filter in your fuel-injected Ford F150. The F150 first used fuel injection with the 1985 8-302 (5.0L) engine.
You should replace the fuel filter at the intervals designated by Ford, which can be found in Chilton’s online database. The intervals vary by year, from 1985 to 2008, from every 15,000 miles to every 30,000 miles. In 2009, Ford started using a filter which is part of the fuel pump module and does not require changing. Changing the filter is a fairly easy, inexpensive way to keep your whole fuel system in good shape.
You’ll just need a replacement fuel filter and a fuel line removal tool. The type of tool will vary by the year of your truck. These tools can be purchased at your local auto parts store.
You’ll also need some disposable rubber or latex gloves since gasoline is tough on skin, safety goggles to avoid getting gasoline in your eyes, and a some sort of catch can, since there will be some gasoline in the old filter.
Before starting any work on or near the fuel system, remember, never smoke anywhere near the fuel system or have any type of flame or spark near it!
You’ll probably have to lift the truck to get to the filter unless it’s a 4×4, in which case you may have enough room to crawl underneath. If you have to lift it, use a good floor jack, not the bumper jack and a good set of jackstands to support it. You can also use a good quality set of drive-on ramps. First things first, make sure your truck’s engine is off and the automatic transmission in Park. Firmly set the parking brake. It’s also a good idea to disconnect the battery ground cable; there may be some old wires which could cause a spark.
The fuel system is pressurized, so you’ll have to relieve that pressure before you open any part of the fuel system. Once again, the way to do this will vary by year. You can find the correct procedure by checking Chilton’s online data base.
Now you’re ready to get started.
The following procedure is general and should apply to most years:
The fuel filter is located mid-way along the inside of the left (driver’s side) frame rail.
Most years have safety clamps at each end of the filter over the fittings. Gently pry these off. You may need a small pry tool to get them to move.
Spread the special release tool open and …
… place the tool on the filter inlet/outlet tube and carefully press the tool inward to release the garter spring on the spring lock coupling and …
… remove the fuel lines from the filter.
Remove the filter from the clamp by pulling it straight out, but be careful, as you can see fuel will most likely spill out of the filter
Push the new filter into the clip. Make sure it is pointing in the right direction. Most new filters have an arrow to help you.
Push the fuel lines onto the filter until you can hear a click. To be sure they’re secure, try pulling on them, gently. If they’re on correctly, put the safety clips back on.
Lower your truck if you had it up on stands or ramps, connect the battery and start the engine. Check the filter and lines for leaks.
