The FASS Titanium Signature Series 165GPH Fuel System for 2011-2014 GM Duramax 6.6L (600-1000HP) addresses the fuel delivery limitations of the factory system. This system is designed to alleviate the stress placed on the CP4 injection system, which often draws fuel under vacuum, potentially introducing air into the fuel supply.
This Titanium Signature Series fuel system, engineered by FASS Fuel Systems, aims to provide reliable aftermarket filtration. Key features and benefits include:
The system is designed to improve cold weather starts, reduce emissions, and enhance fuel volume delivery, contributing to a smoother engine idle and potential fuel mileage improvements. Note that installation on a cab and chassis may require modifications. For high-performance applications, the Bulkheading and Suction Tube kit (STK1002) is recommended to optimize fuel retrieval.
