Pressure Test (supply and vent circuits)
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.
TYPICAL
1. Disconnect air inlet hose
2. Install a hose pincher to vent hose
– Connect pump gauge tester (P/N 529 021 800)
to air inlet hose.
NOTE: This pump is included in the ENGINE LEAK
TESTER KIT (P/N 295 500 352).
– Turn fuel valve to OFF position ( except RFI, DI
and 4-TEC ).
– Pressurize fuel system to 34 kPa (5 PSI).
– If no leaks are found, turn fuel valve to ON po-
sition and pressurize once more.
– If pressure is not maintained locate leak and
repair/replace component leaking. To ease leak
search spray a solution of soapy water on com-
ponents, bubbles will indicate leak location.
NOTE: The system must maintain a pressure of
34 kPa (5 PSI) during 10 minutes. Never pressurize
over 34 kPa (5 PSI).
Reconnect air inlet hose of fuel tank to body.
NOTE: Before removing the hose pincher, block
with your finger the outlet fitting to feel if air is
coming out when removing hose pincher. This will
indicate that pressure relief valve and the outlet
fitting are not blocked.
Remove hose pincher from fuel tank vent hose.
