Disconnect the negative cable at the battery then loosen the fuel tank filler cap to relieve any fuel tank vapor pressure. Wrap a shop towel around the Schrader valve on the fuel rail and remove the dust cap from the valve. Connect the fuel pressure gauge to the Schrader valve. Install the free end of the gauge bleed hose into an approved gasoline container, and open the gauge bleed valve to relieve the fuel pressure.
