About This Product

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 install and does not require tuning!

Why should I replace the factory fuel pump on my LML Duramax?

The factory Bosch CP4 injection pump in 2011-2016 Duramax trucks is known for catastrophic failure, which can destroy your entire fuel system. This kit retrofits the more reliable and robust Bosch CP3 pump, preventing a common failure that can lead to repairs costing over $10,000. — The original Bosch CP4 pump has a design that can, without warning, self-destruct and send metal shavings throughout the high-pressure fuel system. This contaminates the fuel injectors, rails, and lines, requiring a complete system replacement. The BD Diesel Venom Conversion Kit (PN 1050496) is a preventative solution that replaces the CP4 with the trusted CP3 pump architecture used on 2001-2010 Duramax engines. This backdating process provides a significant increase in fuel system durability and peace of mind. It's a critical upgrade for any LML owner who tows, daily drives, or simply wants to avoid a multi-thousand-dollar repair bill.

Does this CP3 conversion kit require ECU tuning?

No, this conversion kit does not require any custom ECU tuning on a stock truck. It includes a special CP3 pump designed to work with the factory LML Duramax engine calibration. — A key feature of the BD Diesel Venom kit (PN 1050496) is its 'no-tune required' design. The included CP3 injection pump is specially modified by BD Diesel to perform correctly with the original factory engine management software. This saves you the added cost and complexity of needing an aftermarket tuner or custom flashing, which is often required with other CP3 conversion kits. The installation is simpler and it ensures that the truck's drivability and emissions systems continue to function as the manufacturer intended. This makes it an ideal bolt-in reliability solution for owners who want to keep their truck's software stock.

Will this kit fit my 2014 Chevy Silverado 2500HD with the 6.6L engine?

Yes, this kit is a direct fit for your truck. It is specifically designed for all 2011-2016 Chevrolet Silverado and GMC Sierra 2500HD & 3500HD models equipped with the 6.6L LML Duramax engine. — The BD Venom CP3 Conversion Kit (PN 1050496) offers comprehensive fitment for the entire LML Duramax platform. It is engineered to integrate seamlessly with your truck's specific engine bay and fuel system layout. Key details include: — • Vehicle Fitment: 2011-2016 Chevrolet Silverado & GMC Sierra 2500/3500 HD • Engine: 6.6L Duramax LML • Kit Components: Includes pre-formed hard fuel lines for an OEM-style installation in the LML engine valley. • Benefit: The kit provides a complete solution without needing to source additional parts for the conversion, ensuring proper fit and function across the entire specified model-year range.

How difficult is the installation and what is the estimated time?

This is an advanced, professional-level installation. BD Diesel estimates the installation time to be approximately 15 hours. — This is not a simple bolt-on part. The injection pump is located deep in the engine valley, and accessing it requires significant disassembly, including the removal of the turbocharger and other top-end engine components. While the kit is designed for a seamless install with pre-formed hard lines and no tuning required, the labor involved is substantial. The 15-hour time estimate reflects the complexity and should be performed by a qualified mechanic or a highly experienced enthusiast with the proper tools and facility. The kit's design, including OEM-style fuel lines and a dedicated feed line for safe routing, helps ensure the process is as straightforward as possible for a job of this magnitude.

What parts are included in the box and is there a core charge?

The kit includes the special no-tune CP3 pump, pre-formed high-pressure hard fuel lines, a fuel feed hard line, and all necessary hardware for installation. There is no core charge for this kit. — This is a complete conversion package (PN 1050496) designed to provide everything needed for the CP4-to-CP3 swap. The centerpiece is the specially calibrated Bosch CP3 pump that works without custom tuning. You will also receive high-quality, pre-bent hard lines that mimic an OEM fit and finish, eliminating the need for custom fabrication. A specific hard line is included for the fuel feed, ensuring safer routing through the hot engine valley. By including all necessary components and not requiring a core to be sent back, BD Diesel simplifies the ordering and installation logistics.

Is this CP3 conversion kit emissions compliant?

Yes, this kit is designed to be EPA emissions compliant. It allows you to retain and properly function all factory emissions equipment on your LML Duramax. — The BD Diesel Venom CP3 Conversion Kit (PN 1050496) carries an EMS Code of 4, signifying it is covered under CARB EO and is legal for sale and use in all 50 states. A critical aspect of this is that the kit does not require any custom tuning, which means it works with the original factory engine calibration that manages the emissions systems. You can install this kit to improve the reliability of your fuel system without removing or disabling any emissions components, making it a suitable upgrade for customers in areas with emissions testing or for those who want to keep their truck compliant with regulations.
