Fuel Pressure Release: Service and Repair
Fuel Pressure Relief
FUEL PRESSURE RELIEF PROCEDURE
TOOLS REQUIRED
J 34730-1A Fuel Pressure Gage
CAUTION: Remove the fuel tank cap and relieve the fuel system pressure before servicing the fuel system in order to reduce the risk of
personal injury. After you relieve the fuel system pressure, a small amount of fuel may be released when servicing the fuel lines, the fuel
injection pump, or the connections. In order to reduce the risk of personal injury, cover the fuel system components with a shop towel before
disconnection. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.
1. Turn the ignition OFF.
2. Disconnect the negative battery cable.
3. Install the J 34730-1A.
4. Loosen the fuel fill cap in order to relieve the fuel tank vapor pressure.
5. Open the valve on the J 34730-1A in order to bleed the fuel system pressure. The fuel connections are now safe for servicing.
6. Place a shop towel under the fuel pressure service port in order to catch any remaining fuel spillage.
7. Once the system pressure is completely relieved, remove the J 34730-1A.
