non-usable portion of the tank which results from the
fuel in the tank that is below the pickup tube and the
ullage area that has been incorporated into your tank.
It is recommended that you follow all instructions
regarding the filling of fuel tanks.
Fuel tanks with levels less than 1/4 full can cause
engine stalling problems due to fuel starvation or by
allowing sediment and dirt to enter the fuel supply
lines. Keep the tank full and monitor the fuel level
often to prevent this from happening.
Fuel Vent
The fuel tank vent is integrated into the fuel fill deck
fitting (See fig. 3.3.1). The VaporTec fuel pressure
management system, (fuel fill deck fitting, integrated
check valve, fill limit vent valve, grade valve), en
-
sures that the fuel system constantly maintains proper
vapor pressure in all situations. This eliminates any
unintended pressure which can seriously damage a
boat or engine. The vent serves as an over pressure/

resting protection. The fuel vent system also plays
an important role in controlling the “FULL” level
of fuel with the use of the FLVV (Fill Limit Vent
Valve). Grade Valves have been added to the tank
which allows proper ventilation of the tank when
the boat is stored, or trailered, on a moderate incline,
without fuel seepage.

This fuel system is designed to automatically shut
off the fuel nozzle when the tank is full, similar to an
automotive fuel system. The tank is filled when the

Fuel gauge only reads accurately
when boat is level (not underway).
The fuel system on this vessel complies with
all applicable ABYC standards. Fueling station
pump flow rates that exceed 18 gallons
(68 liters) per minute may damage system
components and cause fuel leakage into the
vessel.
