Fuel Fill & Vent
• The fuel fill fitting is marked "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.
Anti-siphon Valve (Gas Engine Only)
• 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.
