Introducing the GMC Sierra 2500 HD Fuel Injection Pump Conversion Kit by Wehrli – a crucial upgrade for your `11-`16 model. Designed for the discerning automotive enthusiast, this CP3 Conversion Kit, with its sleek black anodized finish, is a must-have for those equipped with the robust LML 6.6L Duramax Turbo Diesel engine.

This product addresses the notorious weaknesses of the factory-installed CP4.2 pump, which can be easily compromised by minor fuel or water contamination, potentially leading to costly repairs. Our kit, first released in 2013, offers a reliable solution by converting to a more durable CP3 pump setup. Crafted in the USA, it delivers enhanced compatibility, whether your truck remains in its stock state or features light modifications. The plug-and-play design ensures seamless operation without requiring additional tuning when paired with a Bosch OEM 'LBZ style' CP3 pump (sold separately).
