Fuel Pressure Release
Before disconnecting fuelline, release fuelpressure fromfuel
line toeliminate danger.

~ 1.Turn ignition switch"ON".

Remove
fuseforfuel pump.
Start engine.
After engine stalls,crank
it
two orthree times to
release allfuel pressure.
4. Turn ignition switchoffand reconnect fuelpump
fuse.

Fuel Pressure Check
• When reconnecting fuelline, always usenew clamps.
• Make surethatclamp screwdoesnotcontact adjacent
parts.
• Use atorque drivertotighten clamps.
• Use Pressure Gaugetocheck fuelpressure.
• Donot perform fuelpressure checkwithsystem operating.
Fuel pressure gaugemayindicate falsereadings.

1. Release fuelpressure tozero.
2. Disconnect fuelhose between fuelfilter andfuel tube
(engine side).
3. Install pressure gaugebetween fuelfilter andfuel tube.
4. Start engine andcheck forfuel leakage.
5. Read theindication offuel pressure gauge.

At idling:
With vacuum hoseconnected
Approximately 235kPa (2.35 bar,2.4kg/cm

34psi)
With vacuum hosedisconnected
Approximately 294kPa (2.94 bar,3.0kg/cm
2,
43psi)
If
results areunsatisfactory, performFuelPressure Regula-
tor Check.
