2011-2016 Duramax Venom CP3 Conversion Kit W/ Standard Pump (1050496)

Go back to a simpler time, when things worked and you could rely on your Duramax fuel system. Since the introduction of the common rail fuel system in 2001, all Duramax Engines were equipped with a reliable Bosch CP3 high-pressure fuel pump. Then in 2011, GM made major changes and switched to a Bosch CP4 pump which has seen its share of problems.

The CP4 is also susceptible to catastrophic failure. When disaster strikes, the entire fuel system requires replacement after metal debris from the failed pump spreads throughout. Cleaning the tank, replacing lines and injectors, and of course a new pump can end up costing you in excess of $10,000 in repairs. Prevent a costly failure and add durability by backdating your LML Duramax to a CP3 with a conversion kit from BD Diesel. This kit comes with everything you need for installation and does not require tuning!
