Hardware kit

Trucktok "No Pump" kit for the LML CP3 conversion gives you the option to select your own CP3 pump for your application. Our kit provides you with all of the hardware you need to adapt a LBZ/LMM based Bosch CP3 to your 2011-2016.

Protect your LML from the infamous "ticking time bomb"—the factory CP4 pump. Known for sudden, catastrophic failures that can lead to $10,000+ in total fuel system repairs, the CP4 is the weakest link in your engine. Our CP3 Conversion Kit offers a permanent solution by upgrading your truck to the ultra-reliable, high-capacity CP3 architecture used in earlier Duramax models.
