3.2 Fuel System
Fuel Manifold System
Fuel Management System
The outboard fuel system on your Pursuit
has three fuel tanks and a fuel management
system. The fuel manifold is located in the
mechanical space under the hatch in the
cockpit floor. Fuel flow to the engines is con
-
trolled by three four-way valves depending
on engine configuration. The selected tank is
indicated by the position of the point on the
selector valve handle.
During normal operation, each engine should
be running off of its respective tank (refer to
the photo). The valves should be set so that
each engine draws fuel from its respective
tank. If a fuel supply problem should occur
in one of the fuel tanks, any combination of
engines can be temporarily operated from
any tank by opening valves from that tank.
Operating the boat with all fuel valves open to
the starboard or port tank should be avoided.
All boats equipped with gasoline engines are
required to have anti-siphon valves by the
U.S. Coast Guard. The fuel delivery lines are
equipped with anti-siphon valves where the
lines attach to the fuel tanks. These valves
help prevent gasoline from siphoning out of
the fuel tank should a line rupture.
DO NOT remove anti-siphon valves from
system. Anti-siphon valves prevent fuel from
flowing into bilge should a fuel hose or fitting
leak. If the valve becomes clogged, clean and
reinstall or replace it.
Fuel Tanks
The fuel pick-up tubes are positioned in the
tanks to achieve optimum fuel usage, fuel line
routing, etc. At certain speeds and hull trim
angles, the fuel supply at the withdrawal tube
can increase or decrease accordingly. Be
extremely careful when attempting to oper
-
ate 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 pickup tubes.
Fuel Gauge Senders
The fuel gauge senders are more accu-
rate when the boat is stationary and level.
Because of the change in attitude when the
boat is underway, variations in gauge read
-
ings can occur. This system is a relative indi-
cation of the available fuel supply and not a
calibrated instrument.
Fuel Fills
Gasoline fuel fills are located on each gun
-
wale and are marked “GAS”. The starboard
fuel fills feed the starboard and center tanks.
The port fuel fill feeds the port tank. All three
tanks hold approximately 145 gallons each.
Gasoline Fuel Fill
The fuel fill is opened by turning it counter
-
clockwise. 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 damaged replace only with
