Description

The Wehrli Custom Fabrication 2017-2023 L5P Duramax CP3 Conversion Kit is designed for trucks with upgraded turbo kits and injectors that require more fuel delivery than the stock HP4 pump can provide. The 14mm (WCF100458) version is ideal for built competition engines utilizing power adders and custom injectors, aiming to maximize the L5P platform's potential. This kit requires an aftermarket low-pressure CP3 compatible lift pump and custom tuning. It is a racing product for competition use only.
