Fuel System Pressure Relief Procedure

Description:

WARNING:
^ To reduce the risk of fire and personal injury, it is necessary to relieve the fuel system pressure before servicing the fuel system.
^ After relieving fuel 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.
^ Do Not perform this procedure if the engine is hot, for possible damage could be caused to the catalyst.
