The GMC Sierra 3500 HD Fuel Injection Pump Conversion Kit by Wehrli—specifically the CP3 Conversion Kit in Black Anodized for `11-`16 models—is a pivotal product for automotive enthusiasts aiming to enhance the efficiency and reliability of their vehicle's fuel system. It is an exceptional choice for upgrading the fuel pump to mitigate issues common in factory-installed components.

Beneath the hood, original factory CP4.2 pumps have garnered a reputation for their susceptibility to failure due to minor contaminants. With possible repercussions reaching costs upwards of $8,000 for repairs involving new injectors and comprehensive fuel system cleaning, our CP3 Conversion Kit emerges as a proactive solution. Designed and manufactured in the USA, this kit suits both stock and lightly modified trucks without requiring tuning. Pair it with a new Bosch OEM 'LBZ style' CP3 pump (available separately) for optimal results, integrating seamlessly with your vehicle's existing setup.

Features

• Precision-formed, pre-bent CP3 to fuel rail high-pressure lines
• Black anodized CNC machined billet CP3 pump mounting plate
• CNC machined stainless steel high flow CP3 feed & return fuel fittings
• Pre-formed feed and return fuel lines for OEM-like fit and finish
• FCA / MPROP inlet metering valve extension harness
