How do you relieve the pressure on the fuel system on the ford expedition?

Answer 1

Relieving Fuel System Pressure *** A fuel pressure gauge, such as Ford Tool T80L-9974-B, is needed to correctly perform this procedure. *** 1. Disconnect the negative battery cable and remove the fuel filler cap. 2. Remove the cap from the pressure relief valve on the fuel supply manifold. Install pressure gauge T80L-9974-B or equivalent, to the pressure relief valve. 3. Direct the gauge drain hose into a suitable container and depress the pressure relief button. 4. Remove the gauge and replace the cap on the pressure relief valve. *** As an alternate method on models except 1997 F-150, F-250, Expedition and Navigator, disconnect the inertia switch and crank the engine for 15-20 seconds until the pressure is relieved. ***
