SP 13900 19MM & 22MM 6 Point Fuel Line Sockets for Cummins ISX & ISB

This is a set of 2 fuel line sockets for use on ISX and ISB Cummins engines. These are 1/2" drive 6 point sockets sizes 19mm and 22mm. The 19mm socket is for use on the Cummins ISB engines, and the 22mm socket is for use on the Cummins ISX engines. This tool is made to easily torque the lines correctly, reducing if not eliminating, the possibility of a fuel leak or damaging the fuel line, fuel rail, or fittings. The tool will also fit many other engines in the Cummins line-up. The 19mm socket is also available separately as part # SP13920.
