Relieving Fuel System Pressure

Print

Before working on any components of the fuel system, any residual pressure should be relieved first to limit the possibility of injury or fire. This can be done by loosening the service port bolt at the end of the fuel rail. Hold a rag at the fitting to catch the spray, loosen the fuel line bolt, then tighten it again. Do not over tighten the fitting or the copper sealing washer will split.


CAUTION
Most of the following procedures will produce fuel vapors. Make sure there is proper ventilation and take the appropriate fire safety precautions.
