BD Diesel 11-16 Chevrolet Silverado 2500HD /3500HD 6.6L Venom CP3 Conversion Kit C/W Standard Pump
The BD Diesel 1050496 Venom CP3 Conversion Kit with Standard Pump is the definitive upgrade for 2011–2016 Chevrolet Silverado and GMC Sierra 2500HD/3500HD 6.6L LML Duramax owners seeking to eliminate the catastrophic CP4 fuel pump failures that can spread metal debris throughout the system and incur over $10,000 in repairs. It replaces the fragile CP4 with a proven LML-style Bosch CP3 pump for superior reliability, higher fuel volume, and consistent pressure that outperforms the stock setup in durability and performance under heavy towing or high-HP builds.
Featuring a complete bolt-on assembly with billet brackets, high-flow fuel lines, and O-ring sealed fittings, this kit installs without tuning or ECM modifications while maintaining factory drivability and emissions compliance. This ensures Duramax enthusiasts experience zero downtime and enhanced fuel delivery compared to vulnerable OEM configurations. Constructed with corrosion-resistant stainless hardware, it supports up to 600+ HP applications by leveraging the CP3's overdrive gearing, providing a seamless, no-core-charge solution that integrates directly with existing components for maximum longevity better than piecing together individual parts from other sources.
