Water‑Separating Fuel Filter

WARNING

Fuel is flammable and explosive. Ensure 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.

CAUTION

Failure to release pressure from the fuel system will result in fuel spraying out, which can

cause a fire or explosion. Allow the engine to cool completely and release all fuel pressure

before servicing any part of the fuel system. Always protect eyes and skin from

pressurized fuel and vapors.
