BD Diesel Venom CP3 Conversion Kit - 2011-2016 Chevy/GMC 2500HD/3500HD 6.6L LML Duramax

The CP4 pump on the LML Duramax has a reputation, and when it fails it can take the whole fuel system with it. BD's Venom conversion swaps in the proven LMM-style Bosch CP3 pump that Duramax owners trusted for years.

It's a smart move on a high-mile LML or before you start adding power. No tuning is required, and there's no core charge.

Why we like it

• Replaces the CP4 with an LMM-style Bosch CP3
• No tuning required
