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 speci
fi
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 to permit the fumes to escape. While the tank
is
fi
lled, air displaced by the incoming fuel is relieved through the fuel
vent. Once the fuel
fi
ll cover is replaced all domestic EPA compliant
tanks use a charcoal
fi
ter between the tank and vent line. This device
needs no maintenance and lasts
the life of the fuel system.
The fuel fill is located at the
starboard deck.
Your vessel uses a combo type
(internal vent) fuel
fi
ll. Both the
fuel
fi
ll and vent occupy the same
cavity under a protective cover. If
fuel over
fl
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 over
fl
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.
