Ford expedition fuel filter tool

The new fuel filter will need to be positioned with the arrow pointing in the same direction. Then, pull the fuel filter out of the bracket and place it into the drip pan.

Position the new fuel filter into the clamp with the arrow pointing in the proper direction. Tighten the clamp over the fuel filter with the screwdriver. Then, push both fuel lines straight onto the fuel filter ports until each line locks in place.

Once the lines are pushed far enough onto the ports, the plastic clips will lock inside of the fuel lines. Then, slowly pull outward on the fuel lines to ensure that each fuel line is secured to the fuel filter ports. Slide the drip pan out from under the Expedition and screw the gas cap back onto the filler tube until it clicks.

Turn the ignition to the accessory position for about five seconds and then turn it back to the off position. Repeat this a total of three times before cranking the engine. Crank the engine and inspect the new fuel filter for signs of gas leaking around the fuel lines.

Allow the engine to run for about 30 seconds. Then, turn the engine off. The arrow that is imprinted on the side of the fuel filter represents the directgion of fuel flow through the filter. The arrow must point toward the fuel line that is traveling to the engine. No smoking or open flames around any type of fuel. Wear safety glasses or goggles when replacing the fuel filter. Refer to state and local laws that pertain to the discarding of used fuel and used fuel filters.

Before taking anything apart, check to see if your engines computer has any trouble codes saved in it. The engine may throw a P trouble code. Any trouble codes that exist could be a clue. Sometimes when there is low fuel pressure, you may also get an oxygen sensor related trouble code as well.

The real issue with diagnosing a bad fuel filter is that it resembles many other vehicular issues in terms of symptoms. Typically, if you are heading up a hill or accelerating the engine may start to feel like it is just running out of steam.

Now, a bad fuel filter can also feel a heck of a lot like a bad catalytic converter. Both conditions will make the motor feel like it is running out of wind when you hit the gas. A bad catalytic converter will not feel as jarring. If you are unsure, check out this article on troubleshooting catalytic converters. If you get P or P trouble codes with a scanner, it very well may be the catalytic converter causing these symptoms.

One of the best indicators of a clogged fuel filter is going to be that the your Expedition is difficult to start. If your car is difficult to start, a clogged fuel filter would probably not be the place to start looking, especially if you are getting no trouble code for fuel pressure or the oxygen sensors. At the most basic of levels your Ford Expedition needs three things to start: Air, fuel, and spark.

It could certainly cause the problem though. A fuel pump that is going out is going to feel the same as a bad fuel filter. This makes telling if you have a bad fuel pump vs bad fuel filter very challenging. How do you tell them apart? A clogged fuel filter will have high pressure on its input side and low pressure on its output side.

They are both going to cause the same hesitation at high speed and difficulty starting. The only way to truly tell is to place a fuel pressure gauge on both sides of the line and get a reading from both.
