After relieving the system pressure, a small amount of fuel may be released when servicing the fuel lines or connections. In order to reduce the
chance of personal injury, cover the regulator and the fuel line fittings with a shop towel before disconnecting. This will catch any fuel that may
leak out. Place the towel in an approved container when the disconnection is complete.
