Fuel Pressure Release: Service and Repair
Fuel Pressure Relief Procedure
FUEL PRESSURE RELIEF PROCEDURE
TOOL 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.
CAUTION: Refer to Battery Disconnect Caution.
2. Disconnect the negative battery cable in order to avoid possible fuel discharge if an accidental attempt is made to start the engine.
3. Loosen the fuel filler cap in order to relieve the fuel tank vapor pressure.
4. Remove the left engine sight shield.
5. Connect the J 34730-1A to the fuel pressure connection. Wrap a shop towel around the fitting while connecting the gage in order to avoid spillage.
6. Install the bleed hose of the gage into an approved container.
7. Open the valve on the gage to bleed the system pressure. The fuel connections are now safe for servicing.
8. Drain any fuel remaining in the gage into an approved container.
