High-Performance Gen VI LT1/LT4 Low Side Dual Fuel Pump

The Katech High-Performance Gen VI LT1/LT4 Low Side Dual Fuel Pump Module is engineered as a purpose-built fueling solution for Gen VI LT1 and LT4 applications, specifically targeting Gen 6 Camaro and CTS-V3 platforms that require increased low-side fuel capacity without sacrificing factory system functionality. Unlike auxiliary pump systems or modified factory modules, this sealed, drop-in dual pump module retains critical OEM features such as factory returnless fuel system architecture, fuel level sender functionality, EVAP compatibility, and low-level fuel performance. The module is constructed with OE-style materials to maintain proper sealing and system integrity. In dual pump configuration, this system has been tested to support up to approximately 900 RWHP on E85 within a factory-style returnless fuel system. When operated in single pump configuration, it delivers performance comparable to factory high-output applications. The primary fuel pump is controlled by the factory Fuel Pump Control Module (FPCM), while the secondary pump requires an external control strategy, such as a Hobbs switch or standalone controller. Installation is designed as a true drop-in replacement, allowing installation without permanent modification to the fuel tank or system. A post-pump fuel filter (5–10µm, stainless or micro fiberglass, E85 rated) is required for operation. For a complete plug-and-play installation, the Katech External Remote Fuel Filter Kit (KAT-A7844) and the Katech Gen VI LT1/LT4 High-Performance Dual Fuel Pump Controller & Integration Harness (KAT-A7815) are recommended accessories. Some vehicle configurations may require the use of a supplied cap and clamp to properly seal an unused venturi T-fitting port.
