Section 07 FUEL SYSTEM
Subsection 02 (FUEL CIRCUIT)
Pressure Relief Valve
All Models
This valve will eliminate fuel spillage when the wa-
tercraft is upside down. If pressure is built up in fuel
system the valve should open at 10 kPa (1.5 PSI) to
release the pressure.
WARNING
If pressure relief valve is stuck, the pressure
in fuel system will build up and it may cause
fuel leakage in engine compartment.
NOTE: It is a one-way valve with an arrow to indi-
cate the air flow.
Check Valve
Black side of the one-way check valve no. 11 is
the valve outlet. It allows air to get in reservoir.
Baffle Pick Up Filter
Carburetor-Equipped Models
Inspect filter no. 5 of baffle pick up. Clean or re-
place as necessary.
Fuel Tank
All Models
Visually inspect the inside and outside of the fuel
tank necks for crack(s). If crack(s) are existing, re-
place fuel tank no. 1.
Check with your finger to feel the inside and out-
side surfaces of fuel tank. Flex fuel tank necks to
ensure there are no hidden cracks.

NOTE: A fuel tank is comprised of 3 components:
the tank, the fuel pick up neck and the filler neck.
The necks are injection molded and the tank is
then blow molded over the necks. During the
molding process, a small molding seam may ap-
pear on the inner side of the necks at approximate-
ly 4 mm (5/32 in) from the base of the neck. It is a
normal situation to have a molding seam and it
should not be confused with a crack.

ASSEMBLY

Assembly is essentially the reverse of disassem-
bly procedures. However pay particular attention
to the following.
Baffle Pick Up
Carburetor-Equipped Models
Slide adapter no. 8 onto baffle pick up no. 8 until
it stops on rib. Install clamp no. 9.
Install baffle pick up no. 6 into fuel tank and push it
until it sits on fuel tank neck. Install clamp no. 7
and torque both clamps to 3 N•m (27 lbf•in).

FUEL SYSTEM PRESSURIZATION

Whenever doing any type of repair on water-
craft or if any components of the fuel system
are disconnected, a pressure test must be
done before starting engine. Ensure to verify
fuel line ends for damage. Always cut dam-
aged end before reinstallation.
Pressure Test
All Models
Proceed as follows:
– Fill up fuel tank.
– Disconnect air inlet hose of fuel tank from body.
– Install a hose pincher (P/N 295 000 076) on fuel
tank vent hose.
