Warning
Remove the fuel tank cap and relieve the fuel system pressure before servicing the fuel system in order to reduce the risk of personal injury. After you
relieve the fuel system pressure, a small amount of fuel may be released when servicing the fuel lines, the fuel injection pump, or the connections. In
order to reduce the risk of personal injury, cover the fuel system components with a shop towel before disconnection. This will catch any fuel that may
leak out. Place the towel in an approved container when the disconnection is complete.
