REMOVAL & INSTALLATION
On most vehicles covered by this guide, the fuel filter is located in the engine compartment, mounted to the firewall.
- Properly relieve the fuel system pressure as outlined in of this guide.
- If not already done, disconnect the negative battery cable.
- On most models, the job is made easier if the air inlet hose and upper air cleaner housing is removed from the vehicle.
- Cover the hose connection with shop towels to prevent any splash of fuel that could be caused by residual pressure in the fuel pipe line. Hold the fuel filter nut securely with a backup wrench, then remove the banjo bolt on the engine feed line. Disconnect the high-pressure fuel line from the filter. Remove and discard the gaskets.
- While holding the fuel filter nut securely with a back-up wrench, loosen the filter feed pipe flare nut on the bottom of the filter. Separate the flare nut connection from the filter. If equipped, remove and discard the gaskets.
- Remove the mounting bolts and remove the fuel filter. If necessary, remove the fuel filter bracket.
- Install the filter to its bracket only finger-tight. Movement of the filter will ease attachment of the fuel lines.
- Insert the filter feed pipe to the lower connection of the filter and manually screw in the main pipe's flare nut.
- While holding the fuel filter nut with a back-up wrench, tighten the banjo bolt to 22 ft. lbs. (30 Nm). Tighten the flare nut to 25 ft. lbs. (35 Nm), with a back-up wrench on the nut.
- Tighten the filter mounting bolts to 10 ft. lbs. (14 Nm).
- Connect the negative battery cable. Turn the key to the ON position to pressurize the fuel system and check for leaks.
- If repairs of a leak are required, remember to release the fuel pressure before opening the fuel system.
