Fuel Vent

The fuel feed line is equipped with an anti-siphon valve.The valve is

screwed into the fuel tank ﬁ tting at the feed line. The valve is pulled

off its seat by fuel pump pressure as the engine is cranking or running.

It allows a one-way fuel roadway to the engine fuel pump . It prevents

fuel from siphoning out of the tank in the event of a fuel line rupture

or disconnected fuel feed hose. See the fuel tank maintenance chapter

for more speciﬁ c information on the anti-siphon valve location. Never

remove the anti-siphon valve as it is a fuel system safety item.

COMBO FUEL FILL W/

INTERNAL VENT

Anti-Siphon Valve

Fuel tanks are vented overboard for the fumes to escape. While the

tank is ﬁ lled, air displaced by the incoming fuel is relieved through the

fuel vent.

The fuel fill is located at the

starboard deck.

Your vessel uses a combo type

(internal vented) fuel ﬁ ll. Both the

fuel ﬁ ll and vent occupy the same

cavity under a protective cover. If

fuel overﬂ ows through the vent

the design forces it back into the

fuel ﬁ ll hose and tank.

A seasoned skipper will hear a

distinct sound as the tank nears

the “top out” or full mode and

may see fuel overﬂ owing back into the fuel hose through the vent. This

helps avoid any overboard spills which harm the environment. There

is a key that ﬁ ts the fuel ﬁ ll. Use it to secure the ﬁ tting from leaking

fuel. Store the key in a safe place so it can be easily found for fueling.

Check the vent ﬁ ll screen periodically for debris.
