Fuel Pressure Relief Procedure
WARNING:
To reduce the risk of fire and personal injury, it is necessary to relieve the fuel system pressure before servicing fuel system components.
NOTE:
Tool required: J 34730-1.
- Disconnect negative battery terminal to avoid possible fuel discharge if an accidental attempt is made to start the engine.
- Loosen fuel filler cap to relieve tank vapor pressure. Do not tighten until service has been completed.
- Connect gage J 34730-1 to fuel pressure connection. Wrap a shop towel around fitting while connecting gage to avoid spillage.
- Install bleed hose into an approved container and open valve to bleed system pressure. Fuel connections are now safe for servicing.
- Drain any fuel remaining in gage into an approved container.
When repair to the fuel system has been completed, start engine and check all connections that were loosened for possible leaks.
