Replace Car Fuel Filter injection
A vehicles fuel filter is used to keep the fuel that is used in the fuel injection system clean to avoid plugging the fuel injectors and the fuel pressure regulator. The fuel filter should be changed between 20,000 and 30,000 miles depending on driving conditions. First locate and identify the fuel filter, all vehicles are different so you might have to look around for it. Some are under the hood and others are under the car or truck like the one used in this example.

Step 3 - Install Fuel Filter Mount
Remove fuel filter mount from old fuel filter and install it on the new fuel filter. Make sure that the direction arrow is pointing in the direction of the engine. (Forward in most cases)
Step 4 - Install New Fuel Filter

To use the release tool insert the tool over the fuel line near the fuel filter, push the tool inward to release the fuel line from the filter. To reinstall the new filter push the fuel lines onto the new filter, the fuel lines automatically hold onto the new filter.
