Industrial Injection 23S401 CP4 To CP3 Conversion Kit With Pump

Kit came with everything needed for installation. Instructions were nice & clear except that the kit now is updated and the instructions don’t show that the rear fuel line has been deleted and now the rail uses a cap. The rear ECM plug is a pain to get on even as a mechanic who works on these regularly. I would recommend the S&S kit over this one due to the ease of installment, the cheaper price, and no core charge. However, everything in this kit was quality and you are getting a Duramax style 10 mm stroker cp3 pump instead of a standard displacement cp3 so possibly more room to grow power-wise with this over the standard S&S. Unfortunately the pump was shipped and the packaging was spread inside the fitting so I had to remove the fittings and clean them before installation to prevent contamination. I think industrial injection could have put this kit together a little better but as of now the pump works flawlessly after some tuning Order number #1897970
