Fits: 2011-2016 GM LML w/ 6.6L Duramax
This 131003-1 kit by H&S Motorsports will replace the factory CP4 high-pressure fuel pump with a CP3 high-pressure fuel pump. CP3 pumps are commonly found on the older Duramax (and Cummins) platforms and have proven to be much more reliable.
Another benefit of the 131003-1 H&S Kit is it allows the use of highly modified CP3 pumps that can be used to provide a SERIOUS amount of high-pressure fuel flow.
This kit includes a new Stock CP3 pump.
- 1 - Brand New Bosch Stock CP3 Pump
- 1 - Billet CP3 Pump Adapter with O-Ring
- 1 - High-Pressure Fuel Line
- 1 - Low-Pressure Fuel Line
- 1 - Fuel Return Line Block-Off
