Fuel Pressure Relief Procedure

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 unit relieves FP system pressure when the engine is turned "OFF". Therefore, no further pressure relief procedure is required.
