Fuel Fill Cap
Th e fuel fi ll is labeled “gas” and is located
along the starboard aft deck. When fueling
it is important to keep the fi ll nozzle
in contact with the fuel fi ll line since it
decreases static electricity, which may spark
and ignite gasoline vapors. Always use the
recommended fuel octane rating as specifi ed
in your outboard engine owner’s manual. Extinguish all fl ame
producing agents before fueling. Th e fi ll cap leads to the anti-
siphon valve and fuel tank. Ensure that the gas cap ratchets shut
which ensures that vapors are contained within the system.
Anti Siphon Valve
Th e anti-siphon valve at the base of the fuel feed line is pulled off its
seat by fuel pump pressure as the engine is cranking or running. It
forms a one-way fuel roadway by sealing off the fuel feed line from
the fuel fi 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 oft en combined into the fuel fi tting on the deck. Fuel
tanks are vented overboard for the fumes to escape. While the tank
is fi 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 or
stop the nozzle fl ow to keep the fuel from splashing out the vent.
