Katech Gen V LT5 High Flow High Pressure Fuel Pump Bypass Line

Katech Gen V LT5 High Flow High Pressure Fuel Pump Bypass Line

Parallel Port Injection Fuel Feed for High-Horsepower, E85-Fueled LT5 Builds.

The Katech Gen V LT5 High Flow High Pressure Fuel Pump Bypass Line addresses a fuel delivery limitation identified during Katech's development of high-horsepower, E85-fueled LT5 engines. In these applications, Katech observed significant fuel feed pressure drop-off at the port injection rails as fuel demand increased.

Katech's solution supplies the port injection system in parallel with the high pressure fuel system, replacing the factory series feed arrangement. This revised routing is designed to address the port injection supply restriction in demanding LT5 applications.

Constructed from BMRS race-grade fuel hose with pre-crimped fittings, the Katech Gen V LT5 High Flow High Pressure Fuel Pump Bypass Line is designed for Gen V LT5 engines, including the 2019 Chevrolet Corvette ZR1. Installation can be completed in the vehicle without removing the supercharger.
