NOTICE
Use a suitable container to catch any fuel that might
spill. Clean up any spilled fuel immediately.
1. Remove the used fuel filter and discard the used
fuel filter.
2. Clean the gasket sealing surface of the fuel filter
base. Ensure that all of the old gasket is removed.
3. Apply clean diesel fuel to the new fuel filter gasket.
NOTICE
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 acceler-
ated wear to fuel system parts.

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.
