Section 04 FUEL SYSTEM
Subsection 03 (FUEL TANK AND FUEL PUMP)
When the START button is pressed, the electrical
system is powered. The fuel pump will come on
for approximately 2 seconds to pressurize the fuel
rail in preparation for the engine start.
The ECM supplies the ground signal to turn on the
fuel pump motor.
The pressure regulator will ensure appropriate
fuel pressure is supplied to the injectors.
When the ECM receives a signal to shut down
the engine (START/STOP switch, safety lanyard,
or T.O.P.S. sensor) it removes the fuel pump
ground signal.
Fuel Level Indication
An electric float type fuel level sensor is mounted
on the side of the fuel pump reservoir. As the
float moves with changing fuel levels, it varies a
resistance that changes the voltage signal com-
ing fromthe information center (multifunction
gauge).This signal is representative of the fuel
level.
The information center interprets the fuel level
voltage signal that comes back from the fuel level
sensor. It then displays the proper fuel level bars
and a low fuel warning message when required.
The information center will also trigger the beeper
which produces the appropriate beep signal to
warn the driver of a low fuel condition.
The fuel level sensor resistance is at its lowest
value when the fuel tank is full, and at its highest
value when the tank is empty.
Refer to the
FUEL LEVEL SENSOR
in this subsec-
tion for fuel level sensor testing procedures.

The inlet valve is located high in the watercraft to
prevent water entry in fuel tank.
The inlet
valve is a check valve that allows air to
enter fu
el tank to prevent fuel starvation. It also
prevent
s fuel to flow out of fuel tank.

The outlet valve is a pressure relief valve that is
normally closed to prevent water entry in fuel
tank. It also prevents air to flow out.
