Fuel System Pressure Relief Procedure

WARNING:
^ To reduce the risk of fire and personal injury, it is necessary to relieve fuel system pressure before disconnecting fuel line fittings.
^ After relieving system pressure, a small amount of fuel may be released when disconnecting fuel line fittings. In order to reduce the chance of personal injury, cover fuel line 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.
