Fuel filters and elements are serviced by replacement only. Some
vehicle manufacturers recommend fuel filter replacement at 30,000 miles
(48,000 km). Always replace the fuel filter at the vehicle
manufacturer's recommended mileage.

The fuel filter replacement procedure varies depending on the make
and year of the vehicle and the type of fuel system. Always follow the
filter replacement procedure in the appropriate service manual. The
photo sequence below shows a typical procedure for relieving fuel
pressure and removing a fuel filter.


Removing a Fuel Filter on an EFI Vehicle






Disconnect the negative cable at the battery.





Loosen the fuel tank filler cap to relieve any fuel tank vapor pressure.





Wrap a shop towel around the Schrader valve on the fuel rail and remove the dust cap from the valve.





Connect the fuel pressure gauge to the Schrader valve.





Install the free end of the gauge bleed hose into an approved
gasoline container, and open the gauge bleed valve to relieve the fuel
pressure.





Place the vehicle on the hoist and position the lift arms according to manufacturer's recommendations. Then raise the vehicle.





Flush the fuel filter line connectors with water, and use compressed air to blow debris off and away from the connectors.





Follow the recommended procedures for disconnecting the fuel inlet connector.

Installing Fuel Filters


In-line fuel filters are installed in the fuel line. In carbureted
engines, the in-line gasoline filter is usually installed between the
fuel pump and the carburetor. In vehicles with a fuel injection system,
the location of the fuel filter is determined by the manufacturer. An
arrow on the filter shows the direction of fuel flow.

To install a new filter, begin by wiping the male tube ends of the new filter with a clean shop towel.


Apply a few drops of clean engine oil to the male tube ends on the filter.


Check the quick connectors to be sure the large collar on each
connector has rotated back to the original position. The springs must
be visible on the inside diameter of each quick connector.


Then install the filter in the proper direction and leave the mounting bolt slightly loose.


Install the outlet connector onto the filter outlet tube and press
the connector firmly in place until the spring snaps into position.


Grasp the fuel line and try to pull this line from the filter to be sure the quick connector is locked in place.


Then, do the same with the inlet connector.


Now tighten the filter retaining bolt to the specified torque.


Once everything is connected, lower the vehicle, start the engine, and check for fuel leaks at the filter.
