Fuel System Maintenance

Fuel System

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.
IMPORTANT: Use an approved container to collect and store fuel. Wipe up spilled fuel immediately. Material used to contain
spilled fuel must be disposed of in an approved receptacle.
Before servicing any part of the fuel system:
1. Stop engine and disconnect the battery.
2. Perform fuel system service in a well‑ventilated area.
3. Inspect any completed service work for sign of fuel leakage.

Fuel Line Inspection

Visually inspect the fuel line for cracks, swelling, leaks, hardness, or other signs of deterioration or damage. If any of these
conditions are found, the fuel line must be replaced.
Water‑Separating Fuel Filter
The water‑separating fuel filter is a low‑pressure filter that removes debris and water before the fuel reaches the high‑pressure
fuel pump. It is best to service the water‑separating fuel filter when the engine is cold or after the engine has not run for several
hours. Although the engine may not have run for hours, high ambient air temperatures can cause the fuel system to become
pressurized. The amount of pressure within the system is dependent on the type of fuel system installed on the vessel.
Refer to the Inspection and Maintenance Schedule, preceding, for the proper maintenance interval.

Filter Housing Removal

1. Verify the ignition key switch is off and remove the key.
2. Disconnect the batteries.
3. Locate the water‑separating fuel filter on the starboard front side of the engine.
4. Remove the red service cap.
5. Place a rag or towel around the fuel filter housing to prevent the fuel from leaking or spraying.
6. Use the fuel filter removal/installation tool or the shaft of a screwdriver between the lugs on the filter cover and turn the fuel
filter cover counterclockwise to loosen it. Do not remove the cover.
