Fuel Fill & Vent
• Depending on engine type, the fuel fill deck fitting is marked either GAS, or DIESEL.
• If you have problems filling the fuel tank, see if the fuel fill hose or fuel tank vent hose is kinked or collapsed.
• If there are no visible signs of a problem, contact your local dealer.

Gas Engine Fuel Filters

• The fuel pickup tubes, located inside the fuel tank, are equipped with fine mesh screen filters.
• If your boat features MPI engines, there may be an inline fuel filter on each fuel line.
• Also, when supplied by the engine manufacturer, a fuel filter is installed on the engine.
• Periodically replace the fuel filters to make sure they remain clean and free of debris.
• Talk to your selling dealer or local marina about fuel additives that help prevent fungus or other buildup in your
fuel tank.

Anti-siphon Valves (Gas Engines Only)

• If an engine running problem is diagnosed as fuel starvation, check the anti-siphon valve.
• If the valve is stuck or clogged, ONLY change or replace it while the engine is Off.
• NEVER run either engine with its anti-siphon valve removed, except in an emergency.
• The anti-siphon valves are vital fuel system parts.
• If a fuel line ruptures, this valve will prevent the fuel from siphoning from the tank.
• The valves are located on the fuel tank, where the fuel feed lines attach to the tank.
• These valves are spring loaded and are opened by fuel pump vacuum.
