Fuel Vents
Fuel tanks are vented overboard for the fumes to escape. While the
tank is filled, air is displaced by the incoming fuel is relieved through
the fuel vent. When the fuel tank is near or full slow down or stop the
nozzle flow to keep the fuel from splashing out the vent.
There are two types of fuel vents. One style is located near the fuel fill
fitting on the aft deck and is designed to minimize any fuel spillage.
The other type of fuel fill used is a combo type. The fuel fill and the
vent occupy the same cavity under a protected cover. If fuel overflows
through the vent the design forces it back into the fuel fill and tank.

A seasond skipper will hear when the tank is near the top to avoid
any overboard spills which could harm the environment.
Anti-Siphon Valve
The fuel feed line is equipped with an anti-siphon valve at the fuel feed
line tank connector. The valve is pulled off its seat by fuel pump pressure
as the engine is cranking or running. It forms a one- way fuel roadway.
It prevents fuel from siphoning out of the tank in the event of a fuel
line rupture or disconneted fuel feed hose. As you can see they are
important safety items.
