Caution: Relieve the fuel system pressure before servicing fuel system components
in order to reduce the risk of fire and personal injury.
After relieving the system pressure, a small amount of fuel may be released
when servicing the fuel lines or connections. In order to reduce the chance
of personal injury, cover the regulator and the fuel line fittings with a
shop towel before disconnecting. This will catch any fuel that may leak out.
Place the towel in an approved container when the disconnection is complete.

battery cable. Refer to
Battery Negative Cable Disconnection and Connection
in Engine Electrical.

sight shield (2).

pressure.
- Connect the J 34730-1A
to the fuel pressure valve. Wrap a shop towel around the
fitting while connecting the gage in order to avoid spillage.
- Install the bleed hose of the gauge into an approved container.
- Open the valve on the gage to bleed the system pressure. The fuel
connections are now safe for servicing.
