A vehicle's 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 1 - Locate Fuel Filter
Fuel Filter Location
If you are unsure where your fuel filter is located consult a
car repair manual.
Step 2 - Remove the Fuel Filter Connection
Loosen Fuel Filter Connections
Remove fuel filter connections from fuel lines. A small amount of fuel will leak
out when connections are removed. Next remove the fuel filter mounting bracket bolt
and remove filter.
Step 3 - Install Fuel Filter Mount
Transfer Fuel Filter Holder
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
Install New Fuel Filter
After the fuel filter mount is installed reinstall fuel filter. Make sure the
sealing "O" rings are in place, in good condition and free from debris. Remount
filter and reconnect. Start vehicle to check for leaks. Note: some fuel filters
have a release tool to remove the fuel filter like Ford.
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.
