With the application of high pressure common rail fuel injection systems, the fuel line fittings are becoming more difficult to access with standard tools.
This tool is designed 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.
Designed for the ISX engines to apply the factory required torque of 80 ft/lbs
Designed for the ISB engines to apply the factory required torque of 30 ft/lbs
No torque adaptors with complicated calculations
Currently there is no tool on the market to access these fuel line nuts
