Fuel Filter Removal/Installation Tool
7. Slide the filter housing up to release it from the bracket. The fuel hoses have enough slack to remove the filter housing
from the bracket.
Draining the Filter Housing
Fuel is flammable and explosive. Ensure that the key switch is off and the lanyard is positioned so that the engine cannot
start. Do not smoke or allow sources of spark or open flame in the area while servicing. Keep the work area well ventilated
and avoid prolonged exposure to vapors. Always check for leaks before attempting to start the engine, and wipe up any
spilled fuel immediately.
Tip the filter housing and remove the filter cover to drain the fluid into an approved container. Dispose of the fuel according to
local regulations.
Fuel Filter Inspection
The fuel filter is an important component in the fuel delivery system and should be inspected for debris or degradation every
100 hours of operation. Replace the fuel filter when necessary.

mounting tabs into the lock position.
