How to Replace the Fuel Filter on a 2006 F-150


Replacing the fuel filter on your 2006 Ford F-150 pickup is a normal part of the routine maintenance schedule. Unfortunately, truck owners often overlook this key piece of the maintenance puzzle. Once the filter has reached its filtration capacity, it will either begin to plug, reducing fuel economy and engine performance or it will simply allow the contaminants to pass, fouling the fuel rail, fuel injectors and combustion chamber. Neither is a good option for anyone looking to take care of their automotive investment.

Things You'll Need

  • Drop pan
  • Pocket screwdriver
  • New Filter
  • Place the drop pan on the ground below the driver's door. Climb underneath the truck and look on the inboard side of the driver's side frame to locate the fuel filter. The filter connects to the fuel lines, below the driver's seat area.

  • Move the drop pan directly underneath the fuel filter.

  • Pull the fuel line retaining clip out of the front fuel line, where the line meets the filter, using the tip of the pocket screwdriver. Use extreme caution when pulling the clip out as they break easily and you cannot replace them unless you purchase the entire fuel line.

  • Repeat step three on the rear fuel line. Pull the fuel lines away from the filter by hand when done.

  • Pull the fuel filter out of the filter retaining strap by hand and place it in the drop pan. Insert the new filter into the retaining strap, making sure the flow arrow on the filter points towards the engine.

  • Put the front and rear fuel lines on the outlet and inlet of the new fuel filter and carefully push the retaining clips down into their seats until they click into place.

  • Turn the ignition key to the run position and wait ten seconds. Turn the key back to the off position and then to the run position once more for ten seconds before starting the truck.

Tips & Warnings

  • Avoid spilling any gasoline on asphalt as the gasoline will eat away at the oils in the asphalt and create a hole in the surface.
  • Never work on a fuel system while smoking or near open flames.
