- The CP3 pump has been proven to be reliable. This pump technology has been used on the Cummins and Duramax platform for years.
- While the CP4 has the capability of delivering higher pressures, it lacks the volume of the CP3. With both pumps installed, you get the best of both worlds - high pressure and high volume.
- Price. With the CP4 being a newer pump, it is obviously more expensive. By saving on the pumps included with the kit, H&S Motorsports passes that savings directly on to the customer.
- If your fueling demands exceed what the stock CP3 and CP4 are capable of providing, and H&S Motorsports 6.7L Cummins 10MM Stroker pump can easily be used as a replacement while still being able to re-use all fittings and lines included with the kit.
HIGHLIGHTS:
- Ultimate High Pressure Fuel Supply
- Can Support Enough Fuel For 900+HP
