Fuel System Pressure Relief Procedure

Tool Required: J 34730-1, Fuel Pressure Gauge

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 pipes or connections. In order to reduce the chance of personal injury, cover fuel pipe 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.

1. Disconnect negative battery cable to avoid possible fuel discharge if an accidental attempt is made to start the engine.
2. Loosen fuel filler cap to relieve tank pressure. (Do not tighten until service has been completed.)
3. Connect J 34730-1 to fuel pressure connection. Wrap a shop towel around fitting while connecting gauge to avoid spillage.
4. Install bleed hose into an approved container and open valve to bleed system pressure. Fuel connections are now safe for servicing.
5. Drain any fuel remaining in gauge into an approved container.
