The Industrial Injection conversion kit swaps a CP4 pump to a CP3 setup for 2011–2016 Duramax LML engines and includes a 12mm Double Dragon pump rated at 120% over. It provides the pump and associated components required for that CP4‑to‑CP3 conversion, addressing incompatibility between the factory CP4 and the replacement CP3 hardware in these Duramax applications.
