2006-2010 Duramax Dual CP3 Kit w/o Pump (438402)

The Industrial Injection Dual CP3 Kit (without second pump) for the 2006-2010 LBZ/LMM 6.6L Duramax is the bracket, fuel-line, and controller package needed to add a second CP3 alongside the factory pump — minus the pump itself. Add your own second CP3 (modified or stock) and run both pumps in parallel for roughly twice the fuel volume, lower drive load on the factory pump, and consistent rail pressure under heavy fueling.

• Dual CP3 bracket, lines, and controller — no second pump included
• Drops factory CP3 drive load by approximately 50% once a second pump is installed
• Maintains consistent rail pressure for large injectors and high-HP tunes
• Reduces EGTs under sustained load
• Industrial Injection controller manages fuel delivery between the two pumps

• This kit does NOT include a second CP3 pump — you supply your own. For the complete kit with a pump included, see part number DCP3CLBZ/LMM.
