FUEL PRESSURE CHECK

CAUTION: Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.

NOTE:

Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pressure cannot be completely released because this models do not have fuel return system.
Use Fuel Pressure Gauge Kit [SST: (J-44321)] to check fuel pressure.

1.FUEL PRESSURE CHECK

Release fuel pressure to zero.
Connect fuel tube adapter [SST:KV10120000] (B) to quick connector.

Fuel pressure check

A : Fuel pressure gauge
C : Fuel feed hose
: Vehicle front

Turn ignition switch ON and check for fuel leakage.
Start engine and check for fuel leakage.
Read the indication of fuel pressure gauge

At idling : Approximately 350 kPa (3.57 kg/cm2, 51 psi)

Is the inspection result normal?

YES >> INSPECTION END

NO >> GO TO 2.

2.CHECK FUEL HOSES AND FUEL TUBES
