18 CHAPTER 4: PROPULSION & RELATED SYSTEMS
Fuel System
Fuel Fill and Vent
•
The fuel fill fitting is marked “GAS”.
•
The fuel tank vent is located below the fuel fill.
•
If you experience difficulty filling the fuel tank, check to see that the fuel fill hose and vent hose are free of
obstructions and kinks.
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.
•
Consult with your selling dealer or local marina concerning fuel additives that help to prevent fungus or other
buildup in your fuel tank.
Anti-siphon Valve
•
The fuel system is equipped with an anti-siphon valve.
•
The 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.
•
This valve will prevent fuel from siphoning from the tank in the event of a fuel line rupture.
FIRE, EXPLOSION AND OPEN FLAME HAZARD!
•
It is very important that the fuel system be inspected thoroughly the first time it is filled and
at each subsequent filling.
•
The fueling instructions in the Cruiser & Yacht Owner’s Manual and the fuel recommenda-
tions in the engine operation manual must be followed.
WAR NI NG!

CAUTION
Avoid the storage or handling of gear near the fuel lines, fittings and tank.

N OT I C E
•
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.
