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:

If results areunsatisfactory, performFuelPressure Regula-
tor Check.

Fuel Pressure Regulator Check

1. Stop engine anddisconnect fuelpressure regulator vacuum
hose fromintake manifold.
2. Plug intake manifold witharubber cap.
3. Connect variablevacuumsourcetofuel pressure regulator.
4. Start engine andread indication offuel pressure gaugeas
vacuum ischanged.

Fuel pressure shoulddecrease asvacuum increases. Ifresults
are unsatisfactory, replacefuelpressure regulator.
