DHD 007-1260 Duramax Cummins High Flow 1/2" CP3 Fitting
Get the most potential out of your fuel system with the DHD high flow CP3 inlet fitting. The larger fitting will also help by eliminating possible cavitation damage to CP3 pump from excessive suction required by high pressures of the CP3 pump. The key is the larger inner diameter of the DHD fitting, which allows fuel to flow 70+% more efficiently than with the restrictive stock unit. With a greater volume of fuel on tap, the CP3 pump will be able to perform at its optimum efficiency. If you are running a modified CP3 pump or a stroker CP3, this fitting is required by the pump builders.
