Chapter 3:
FUEL SYSTEM
3.1 General
The fuel system used in Wellcraft boats is designed
to meet or exceed the requirements of the U.S.
Coast Guard, the National Marine Manufacturer’s
Association, and The American Boat and Yacht
Council in effect at the time of manufacturer.
All fuel systems have been factory inspected and
pressure tested in accordance with regulations in
effect at the time of manufacture. This inspection
assures that the system is air tight, leak proof and
safe. It is the responsibility of the purchaser to
maintain it in that condition. Make frequent
inspections to assure that no deterioration or
loosening of connections is resulting from vibration.
Fuel Withdrawal Tube
The fuel withdrawal tube is positioned in the fuel
tank to achieve optimum fuel usage, fuel line
routing, etc. At certain speeds and hull trim angles,
the fuel supply at the withdrawal tank location can
increase or decrease accordingly. Be extremely
careful when attempting to operate the boat when
low on fuel. Though some fuel may be in the tank,
the relative trim angle of the boat may cause the
fuel to flow away from the withdrawal tube.
There is an on/off valve for the supply lines located
on the rear of each fuel tank near the withdrawal
tube. The valve provides a means to turn off the fuel
supply when servicing the fuel system. The small
access hatch provides access to the fuel valve, and
fuel gauge sending unit. The fuel filters are accessed
through access hatches at the rear of the boat.
Fuel Gauges
The fuel gauges indicate the amount of fuel in the
tanks. Due to the mechanical nature of the fuel
sender, variations in reading during various speeds
of operation may occur. This system is merely a
relative indication of the available fuel supply and
not a calibrated instrument.
Your boat is equipped with one fuel gauge sender.
There are analog or digital fuel gauges at the helm
that monitor the fuel level.
Fuel Fill
Fuel fill deck plate is located on the starboard gunnel
and is marked “GAS”. The fuel fill is opened by
turning it counter clockwise with a special key. After
fueling, install the fuel cap and tighten with the key.
Be sure to use the proper type and grade fuel. Refer
to the engine owner’s manual for additional
information.
Note: Do not over tighten the fuel cap. If the
cap is over tightened, the O-ring seal
could be damaged allowing water to
contaminate the fuel system.
3.2 Engine Fuel Supply System
The fuel system includes a fuel tank, water
separating fuel filter and a manual “ON/OFF” fuel
valve at the pickup tube on the fuel tank. The valve
is off when the handle is perpendicular to the fuel
flow. The fuel filter is located in the stern bilge just
below the splash well.
The fuel valve is located on the top rear of the fuel
tank. The valve should be open unless it needs to be
closed in the event of a fuel leak or to service the
fuel system.
Fuel withdrawal line is equipped with a manual shut
off valve where the line attaches to the fuel tank.
These valves prevent gasoline from siphoning out of
the fuel tank should a line rupture.
Fuel Filter
The filter is a spin on, water separator type. It is
recommended that the filter is inspected periodically
and the elements changed at least once every year
or as necessary.
See Fuel System maintenance and the engine
owner’s manual for additional information on the
fuel filters.
