Fuel Fill And Vent; Fuel Filters; Anti-Siphon Valve - Bayliner 175 Owner's Manual

175 • Owner's Manual Supplement

Fuel Fill and Vent

• The fuel fill/vent fitting is marked "GAS".
• If you experience difficulty filling the fuel tank, check to see if the fuel fill hose is kinked or collapsed. If there are
no visible signs of a problem, contact your local dealer.

Fuel Filters

• The fuel pickup tube (located inside the fuel tank) is equipped with a fine mesh screen filter.
• 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
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 fuel system has an anti-siphon valve that prevents fuel from siphoning from the tank if a fuel line ruptures.
• This valve is located at the point where the fuel feed line attaches to the fuel tank.
• The valve is spring loaded and is opened by fuel pump vacuum.
