Fuel Pressure Release: Service and Repair
Fuel supply lines on EFI engines will remain pressurized for sometime after the engine is turned off. This residual pressure must be relieve before
servicing the fuel system. Fuel system pressure may be relieved by one of two methods. The first method is to disconnect the inertia fuel shutoff switch
and crank the engine for 15 seconds. The second method is to install fuel pressure relief tool No. T80L-9974-B or equivalent to measuring port on
engine fuel rail. Position drain hose in suitable container, then depress relief button.
