Fuel Pressure Release: Service and Repair

Tools Required
J 34730-1A Fuel Pressure Gauge

Caution:
- In order 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 pipes or connections. In order to reduce the chance of personal injury, cover fuel pipe fittings with a shop towel before disconnecting the fuel pipes in order to catch any fuel that may leak out. Place the towel in an approved container when the disconnect is completed.
