Fuel Pressure Release: Service and Repair
WARNING:
-
To reduce the risk of tire and personal injury, it is necessary to relieve fuel system pressure before disconnecting fuel pipe fittings.
-
After relieving system pressure, a small amount of fuel may be released when disconnecting fuel pipe fittings. In order to reduce the
chance of personal injury, cover fuel pipe fittings with a shop towel before disconnecting, to catch any fuel that may leak out. Place the
towel in an approved container when disconnect is completed.
FUEL SYSTEM PRESSURE RELIEF PROCEDURE
A constant bleed feature in the pressure regulator relieves pressure when engine is turned "OFF."
1. Disconnect negative battery terminal to avoid possible fuel discharge if an accidental attempt is made to start the engine.
2. Loosen fuel filler cap to relieve tank vapor pressure.
3. The internal constant bleed feature of TBI relieves fuel pump system pressure when the engine is turned "OFF." Therefore, no further pressure
relief procedure is required.
