Industrial Injection 436408 Dual Fuel Pump Kit GM 6.6L Duramax 2011-2016

The Industrial Injection 436408 is a complete dual fuel pump kit designed for 2011–2016 GM 6.6L Duramax diesel engines. This kit addresses one of the most common fuel delivery challenges on high-performance and high-mileage Duramax applications by supplying a supplemental lift pump alongside the factory fuel system, ensuring consistent and adequate fuel volume and pressure to the injection system under all load conditions.

Upgrading to a dual fuel pump setup is a proven solution for modified or hard-working Duramax trucks where the OEM single-pump configuration may struggle to keep up with demand — particularly under towing, hauling, or performance-tuned conditions. Improved fuel delivery helps protect costly injectors and the CP4 or CP3 high-pressure injection pump from cavitation and starvation damage.

Key Features:

• Complete dual fuel pump kit — includes pump
• Engineered specifically for 2011–2016 GM 6.6L Duramax diesel engines
• Increases fuel delivery volume and maintains consistent fuel pressure
