FUEL PRESSURE
(when installing safety
lanyard)
GTI RFI Series and
3D Series
386 - 414 kPa
(56 - 60 PSI)
Disconnect the fuel pressure gauge and reconnect
it.
Crank or start engine and observe fuel pressure.
The fuel pressure should be the same as above.
If pressure is good, fuel pump and pressure regu-
lator are working adequately.
A rapid pressure drop indicates leakage either
from the fuel rail or from the fuel pump check
valve. Check fuel rail for leaks. If it occurs while
installing safety lanyard on DESS and fuel rail is
not leaking, then replace fuel pump.
A slow pressure drop indicates leakage either
from the fuel injector or from the fuel pressure
regulator. Check fuel injector for leaks. If it is not
leaking then replace fuel pump module.
Remove pressure gauge and reinstall fuel hose.

el is flammable and explosive under certain

area.
