Glacier Diesel -6AN High Flow CP3 Pump Inlet 07.5-18 Dodge 6.7L Cummins

When you're trying to squeeze out additional fueling on your 6.7 Cummins, every aspect needs to be looked at, whether its the lift pump, injection pump, larger injectors, or just tuning. One often overlooked area is that of the CP3 pump inlet fitting that's grossly undersized if you've upgraded any of your other fueling components. This high flow metric adapter from Rattlin' Truck & Tractor will help reduce another bottleneck by upgrading the inside diameter from 0.185" to 0.300", nearly double the size!
