Fuel System Pressure Relief Procedure
TOOL REQUIREDJ34730-1 Fuel Pressure Gauge or equivalent.
WARNING: To reduce the risk of fire and personal injury, it is necessary to relieve the fuel system pressure before servicing fuel system components.
After relieving system pressure, a small amount of fuel may be released when servicing fuel lines or connections. In order to reduce the chance of personal injury, cover fuel line fittings with a shop towel before disconnecting, to catch any fuel that may leak out. Place the towel in an approved container when disconnect is completed.
PROCEDURE
1. Disconnect the negative battery cable, to avoid fuel pump turn "ON," if an accidental attempt is made to start the engine.
2. Loosen the fuel filler cap to relieve tank vapor pressure.
3. Connect the fuel pressure gauge to the pressure connection. Wrap a shop towel around the fitting while connecting the gauge to avoid spillage.
4. Install bleed hose into an approved container and open the valve to bleed the system pressure. Fuel connections are now safe for servicing.
5. Drain any fuel remaining in the gauge into an approved container.
INSPECT
When repair to the fuel system has been completed, START the engine and check all connections that were loosened for leaks.
