3.2 Fuel System
Fuel Valves Forward Tank (Typical)
Fuel Valves Aft Tank (Typical)
The fuel system on your Pursuit boat has
two fuel tanks and four manual “ON/OFF”
fuel valves. Refer to the Schematics section.
The fuel valves for the aft tank are located
through the hatch in the cockpit floor and the
fuel valves for the forward tank are located
through a deck plate forward of the leaning
post. Access to the valves on the ST 310 is
through the tackle locker under the helm
seats. Remove the pins in the locker and
pull the locker out of the seat base. The
valves are off when the handle is perpendic-
ular to the fuel flow. The fuel valves allow the
operator to run the engines from both tanks
or from the aft tank or forward tank.
Operating the boat with all four, fuel valves
open, is not recommended and should be
avoided. The engines will not draw fuel
equally from the fuel tanks when both
engines are operating from both tanks The
fuel delivery lines are equipped with anti-
siphon valves where the lines attach to the
fuel tanks. These valves help prevent gaso-
line from siphoning out of the fuel tank
should a line rupture.
All boats equipped with gasoline engines are
required to have anti-siphon valves by the
U.S. Coast Guard. 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.
3.3 Fuel Management
C 280 and S 280
The port fuel fill, feeds the forward tank. The
starboard fuel fill, feeds the aft tank. During
normal operation, the port engine fuel supply
is from the forward tank and the starboard
engine fuel supply is from the aft tank. The
fuel valves on each tank are labeled port
(red) and starboard (green). The labels refer
to the engine the valves supply. If a fuel sup-
ply problem should occur, both engines can
be operated from either fuel tank by opening
both valves on that tank. In the event a fuel
supply problem should occur, resolve the
problem immediately. Operating the engines
on one tank should be done temporarily,
since the engines will consume from the
selected fuel tank only.
C 310 and ST 310
On the C 310 the port fuel fill, feeds the aft
tank and the starboard fuel fill, feeds the for-
ward tank. On the ST 310 both fills are on
the port side and match the orientation of the
fore and aft tanks. During normal operation,
the port engine fuel supply is from the aft
tank and the starboard engine fuel supply is
from the forward tank. The fuel valves on
each tank are labeled port (red) and star-
board (green). The labels refer to the engine
the valves supply. If a fuel supply problem
should occur, both engines can be operated
from either fuel tank by opening both valves
on that tank. In the event a fuel supply prob-
lem should occur, resolve the problem
immediately. Operating the engines on one
tank should be done temporarily, since the
