The FASS Fuel Systems 5/8" Fuel Module Suction Tube Kit (STK1003) provides a modified fuel suction and return point for FASS Titanium Signature Series Systems. This kit, designed for universal applications including Ford Powerstroke, GM/Chevy Duramax, and Dodge/RAM Cummins, addresses potential fuel delivery issues.
Note: STK1003 / STK1003B kit is not compatible with 2003-2004 Dodge applications.
The kit features a bulkhead fitting machined from 6061 T-6 billet aluminum and a Viton convoluted suction tube. This design allows the tube to function as both a suction point and a fuel return port, pulling fuel from within the factory fuel module. This method improves fuel volume delivery compared to the original factory pickup tube.
Bulkhead and Convoluted Suction Tube Features:
This product is recommended for use with FASS Titanium Signature Series Systems. The larger 5/8" suction tube optimizes fuel delivery, making it suitable for high-volume fuel systems. It is also compatible with FASS Competition Series and Industrial Series systems.
