GM 2011-2014 6.6L Duramax FASS 165gph Signature Series Fuel Supply System
This system is recommended for moderate to extreme applications 600 - 800 HP. With this much flow there may be issues with running the fuel tank below ¼ full. The fuel sump kit is recommended to reduce restriction in the factory pickup and eliminate the low fuel level issues.
The Signature Series uses the same motor and blueprint as the larger HD Series just in a smaller package. It is designed for the pickup while utilizing all the best features of the HD series. The Titanium Series now offers flow rates up to 260gph! This size difference allows you to tuck the pump closer to the frame for better clearance and less visibility without sacrificing any of the features known to FASS systems. The Platinum will work well from stock, all the way to extreme performance applications!
