Fig. 2: Fuel pressure can be checked and/or released using an inexpensive pressure/vacuum gauge

  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 49 UN01 010 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.

    NOTE: As an alternate method, disconnect the inertia switch and crank the engine for 15–20 seconds until the pressure is relieved.
