Service Precautions for Fuel Pressure Release during Cylinder Head Assembly
Fuel Pressure Release: Service and Repair
1. Remove fuel tank filler cap to relieve any pressure in the tank.
CAUTION: Fuel supply lines on vehicles with fuel injected engines will remain pressurized for long periods of time after engine shutdown. The
pressure must first be relieved.
WARNING: Before removing fuel tank filler cap, turn fuel tank filler cap 1/4 to 3/4 turn counterclockwise and wait for tank pressure to
relieve. Personal injury may result if fuel tank filler cap is removed without pressure relieved fully.
2. When servicing the fuel lines, loosen the fuel fitting to allow any residual fuel line pressure to be relieved.
