255 Cruiser • Owner's Manual Supplement
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.

Anti-siphon Valve (Gas Engine 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 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 prevents the siphoning of fuel 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.

Gas Engine Fuel Filters

• The fuel pickup tube, located inside the fuel tank, is equipped with a fine mesh screen filter.
• Also, when supplied by the engine manufacturer, a fuel filter is installed on the engine.
• Periodically replace the fuel filter to make sure it remains 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.
