Subsection 01 (FUEL TANK AND FUEL PUMP)
Pressure Relief Valve
This valve no. 17 will eliminate fuel spillage when
the watercraft is upside down. If pressure is built
up in fuel system the valve should open to release
the pressure.
PRESSURE RELIEF VALVE
MODELS PRESSURE
All 4-TEC 3.5 kPa (0.5 PSI)

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
Check if the check valve no. 18 functions properly.
Black side of the one-way check valve is the valve
outlet. It allows air to get in reservoir.
Fuel Tank
Visually inspect the inside and outside of the fuel
tank necks for crack(s). If crack(s) are existing,
replace fuel tank no. 6.
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.
