Chapter 4: Propulsion & Related Systems

Fuel Filters

• The fuel pickup tube, located inside the fuel tank, is equipped with a fine mesh screen filter.
• If your boat features an MPI engine, the fuel system has an inline fuel filter on the fuel line.
• In addition, 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
gas fuel tank.

Anti-siphon Valve

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