Tools Required
J 34730-1A Fuel Pressure Gage. See Special Tools and Equipment .
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.
- Disconnect the negative battery cable. Refer to Battery Negative Cable Disconnect/Connect Procedure (Single Battery) or Battery Negative Cable Disconnect/Connect Procedure (Auxiliary Battery) in Engine Electrical.
- Install the J 34730-1A . Refer to Fuel Pressure Gage Installation and Removal .
- Loosen the fuel fill cap in order to relieve fuel tank vapor pressure.
- Open the valve on J 34730-1A in order to bleed the system pressure. The fuel connections are now safe for servicing.
- Drain any fuel remaining in the gage into an approved container.
- Once the system is completely relieved, remove the J 34730-1A .
