Fuel System
the deck or hull during filling operations. Residual
fuel left on the deck and hull sides can be dan-
gerous and will yellow the fiberglass or damage
the striping.
Be sure to use the proper type and grade fuel.
Refer to the engine owner’s manual for additional
information.
WARNING
DO NOT CONFUSE FUEL FILL WITH THE WATER FILL DECK
PLATE. IF GASOLINE IS ACCIDENTALLY PUMPED INTO
THE WATER TANK, DO NOT ATTEMPT TO PUMP IT OUT
YOURSELF. WATER PUMPS ARE NOT DESIGNED TO PUMP
FUEL AND A FIRE OR EXPLOSION COULD RESULT. CONTACT
YOUR DEALER OR THE CREVALLE CUSTOMER SERVICE
DEPARTMENT FOR ASSISTANCE IN HAVING THE FUEL
PROFESSIONALLY REMOVED.
Fuel Tank Vent
In order to comply with U.S. EPA regulations, the
fuel tank is equipped with a special vent located
on the hull side and vent system emission control
components. A carbon filled canister in the vent
hose between the fuel tank and the vent absorbs
fuel vapors before they can escape to the atmo-
sphere and returns them to the fuel tank.
Carbon canisters can be damaged if they are re-
peatedly exposed to liquid fuel. Special valves in
the vent system and the automatic shutoff valve
on marina fuel pump nozzles prevent the tank
from being overfilled and forcing fuel into the vent
system. You should never attempt to “top off” the
tank after the pump nozzle shutoff has activated.
This could force fuel into the vent system that can
damage the carbon canister or other components.
5.2 Engine Fuel Delivery System
The fuel system has one fuel tank. The Fuel with-
drawal line is equipped with an anti-siphon valve
where the line attaches to the fuel tank. This valve
prevents gasoline from siphoning out of the fuel
tank should a line rupture.
WARNING
DO NOT REMOVE THE ANTI-SIPHON VALVE FROM THE
SYSTEM. SHOULD THE VALVE BECOME CLOGGED, CLEAN
AND REINSTALL OR REPLACE.
Typical Yamaha Engine Fuel Filter
Typical Fuel System Primer Bulb
The fuel filter is installed in the stern bilge of the
boat. It is accessed through a hatch below the
aft seat. The filter is the water separator type
and should be serviced frequently to assure an
adequate supply of clean, dry fuel to the engine.
It is recommended that the filter be inspected
periodically and the element changed as needed.
There is a primer bulb in the fuel line located near
the fuel filter that is used to prime the fuel system
after service or as required. See Fuel System
Maintenance and the engine owner’s manual for
additional information on the fuel filter and the
outboard engine fuel system.
