I'm looking to buy a used LB7 pump to use on my dual CP3 Kit. Any help will be greatly appreciated. Thanks.

 

The ones from dodge trucks seem to be cheaper then the duramex pumps. I have had good luck with eBay. Otherwise expect to pay $700+

The only major difference between the duramax and cummins cp3s is the fitting on the output. If you a fabricating this kit yourself then that shouldnt be a problem. If not then I would stick with the duramax pumps
