Fuel System
3.1 General
The fuel system of your Pursuit boat is
designed to meet the requirements of the
U.S. Coast Guard, Environmental Protection
Agency (EPA), National Marine Manufactur-
ers Association (NMMA), and American
Boat and Yacht Council (ABYC) in effect at
the time of manufacture.
Pursuit Boats has engineered an improved
fuel tank fill and vent system that will reduce
or eliminate fuel spillage when re-fuelling the
boat with a standard automatic shut-off fuel
fill nozzle provided by marinas and gas sta-
tions. This is in accordance to EPA regula-
tions.
While this system provides a clean consis-
tent refueling experience, it still requires the
operator’s attention and must not be
defeated by attempting to over-fill the tank
with fuel. This system will automatically pro-
vide the proper air space (approximately 5%
of total tank volume) in the fuel tank to
accommodate the expansion of fuel during
daily temperature cycles.
This new EPA compliant fuel system is engi-
neered to vent through a carbon canister
when the fuel cap is installed. This will
greatly reduce fuel vapors that escape to the
atmosphere and reduce the fuel odor that
was present on traditional systems. For that
reason, the fuel cap has been changed to
help the operator verify the cap is properly
closed.
Fuel Tanks
The positioning of fuel withdrawal tubes in
fuel tanks are set to achieve optimum fuel
usage, fuel line routing, etc. At certain
speeds and hull trim angles, the fuel supply
at the withdrawal tube location can increase
or decrease accordingly. Be extremely care-
ful when attempting to operate the boat
when low on fuel. Though some fuel may be
in the tank, the trim angle of the boat may
cause the fuel to flow away from the with-
drawal tube(s).
Fuel Gauge Senders
Fuel gauge senders are most accurate when
the boat is stationary and level. Due to the
ever-changing attitude of the boat when
underway, variations in readings may occur.
This system is merely a relative indication of
the available fuel supply and not a calibrated
instrument.
Fuel Fills
A fuel fill is located on each gunwale and is
marked “GAS.” The fuel fill is opened by
turning it counterclockwise. After fueling,
screw the cap on in a clockwise direction
until an audible click is heard indicating that
the cap is seated. If the cap is lost or dam-
aged replace only with original equipment.
During refueling the tank vents out at both
the fuel fill plate and the vent located on the
side of the hull. Note: There should not be
any residual fuel at the vent but there could
be residual fuel at the deck fill plate. Do not
block or restrict either of these vents. Fill the
fuel tank slowly and monitor the fuel gauge
while filling.
Once fueling is completed wash the areas
around the fuel fill(s) to help reduce discolor-
ation of the fiberglass or striping. Use only
!
DANGER
Do not let an odor of gasoline go
unchecked. If the odor of gasoline is
noted, immediately shut off all
engines and electrical equipment.
Have all passengers put on personal
flotation devices and keep a fire extin-
guisher ready. Investigate and correct
the situation immediately.

NOTICE
Certain bulkhead areas are sealed in
accordance with U.S. Coast Guard
regulations that were in effect at the
date of manufacture of the boat.
Ensure all modifications to bulkheads
meet U.S. Coast Guard regulations.
