(1) Secondary fuel filter
Use a suitable container to catch any fuel that might spill. Clean up any spilled fuel immediately.
Remove the used fuel filter and discard the used fuel filter.
Clean the gasket sealing surface of the fuel filter base. Ensure that all the old gasket is removed.
Apply clean diesel fuel to the new fuel filter gasket.
Do not fill the fuel filters with fuel before installing the fuel filters. The fuel will not be filtered and could be contaminated. Contaminated fuel will cause accelerated wear to fuel system parts.
Install the new fuel filter. Spin the new fuel filter onto the fuel filter base until the gasket contacts the base. Tighten the fuel filter by hand by one full turn. Do not overtighten the fuel filter. Use the rotation index marks that are on the fuel filter as a guide for proper tightening.
Prime the fuel system. Refer to the Operation and Maintenance Manual, "Fuel System - Prime" for information on priming the fuel system.
