Testing Fuel Pump Pressure; Fuel System (Cont'd) - SeaDoo GTX Series 2022 Shop Manual

Section 04 FUEL SYSTEM
Subsection 02 (FUEL TANK AND FUEL PUMP)
FUEL TANK LEAK TEST
PRESSURE
21 kPa (3 PSI)
If the pressure drops, locate fuel leak(s), repair/re-
place leaking component(s) and retest.
Possible leak areas are:
– Filler neck, hose and connections
– Fuel tank
– Fuel tank neck
– Fuel pump gasket
– Fuel pump check valve (unlikely).
To locate a leak, check for a fuel smell or leaking
fuel.
If a leak is not visible, spray a soapy water solu-
tion on components to ease locating the leak(s);
bubbles will indicate the leak location(s).
NOTE: If the pressure drops and no leak has been
found, it is possibly fuel pump check valve.
NOTICE
When the fuel system leak test is
completed, thoroughly rinse all components
of the soapy water solution with clear water.
A soapy water residue may cause premature
deterioration and must be rinsed away.
WARNING
If a leak is found, do not start the engine.
Wipe off any fuel that leaked and ventilate
the hull thoroughly to remove any accu-
mulated fuel vapors. Do not use electric
powered tools on watercraft unless system
has passed the leak test.
10. Remove test cap.

TESTING FUEL PUMP PRESSURE

Preparation
The pressure test will show the available pressure
at the fuel pump outlet. It validates the pressure
regulator, the fuel pump and check valve and it
tests for leaks in the system.
1. Ensure the battery is fully charged, refer to
CHARGING SYSTEM
2. Ensure hoses and fittings are not leaking. Re-
pair any leaks.
3. Ensure there is enough gas in the fuel tank.
4. Disconnect the pressure outlet hose from the
fuel pump.
