Fuel Pressure Release: Service and Repair
PROCEDURE:
NOTE: A constant bleed feature in the pressure regulator relieves pressure when engine is turned "OFF."
-
Disconnect negative battery terminal to avoid possible fuel discharge if an accidental attempt is made to start the engine.
-
Loosen fuel filler cap to relieve tank vapor pressure.
-
The internal constant bleed feature of the TBI relieves fuel pump system pressure when the engine is turned "OFF." Therefore, NO further
pressure relief procedure is required.
