Fuel System Pressure Relief Procedure

After relieving fuel system pressure, a small amount of fuel may be released when servicing fuel pipes or connections. In order to reduce the risk of personal injury, cover fuel pipe fittings with a suitable shop towel before disconnecting to catch any fuel that may leak.
1. Disconnect battery ground cable, then loosen fuel filler cap to relieve tank pressure.
2. Connect fuel pressure gauge tool No. J 34370-1 or equivalent to fuel pressure connection. Wrap fitting in suitable shop towel.
3. Install bleed hose to suitable container, then open valve and bleed off pressure.
4. Disconnect fuel pressure gauge, then drain gauge in suitable container.
