Anti Siphon Valve
e anti-siphon valve at the base of the fuel feed line is pulled o its
seat by fuel pump pressure as the engine is cranking or running. It
forms a one-way fuel roadway by sealing o the fuel feed line from
the fuel tting. It prevents fuel from siphoning out of the tank in the
event of a fuel line rupture, or disconnected fuel feed hose. It is an
important safety item, so DO NOT remove the anti-siphon valve.
Fuel Vent
Fuel vents are o en combined into the fuel tting on the deck. Fuel
tanks are vented overboard for the fumes to escape. While the tank
is lled with fuel, air is displaced by the incoming fuel, and relieved
through the fuel vent hose. When the fuel tank is near full, slow
down or stop the nozzle ow to keep the fuel from splashing out
the vent.
Fuel Hoses
Fuel hoses transport gasoline from one component to another.
hoses are required to be of certain diameters in order to comply
with engineering and environmental standards. Hose clamps are
o en used to seal the hose to a tting, and these connections should
be checked regularly along with the entire system at least yearly.
Fuel Pumps/ Filter
From the fuel tank, gasoline is moved from the tank to the engine
by the pressure produced by fuel pumps. One fuel pump is used
to move fuel from the fuel tank to the fuel lter, while a second
pump will pump ltered fuel to each cylinder in the engine block.
