Chevy Silverado and GMC Sierra pickup trucks with the 6.6LM Duramax diesel engine do not have a stock lift pump. This forces the injection pump to “pull” the fuel all the way from the tank, creating a vacuum and constantly introducing more air and vapor into your fuel. The FASS Dura-Max Flow Enhancer Pump creates a postive flow of fuel, “pushing” it to your injection pump, eliminating vacuum and drastically reducing air and vapor in your fuel.

Duramax Flow Enhancer System Features:

  • Reduces Factory CP3 Workload
  • Delivers 120 GPH Fuel at 8-10 PSI Pressure
  • Improves Fuel Flow
  • Improves Fuel Delivery and Performance
  • Reduces Air and Vapor
  • Budget Minded Alternative to Titanium Signature Series
  • Simple Installation

The Dura-Max Flow Enhancer from FASS is modeled after their hugely successful Dodge Direct Replacement Pump series and is now available for your GM Duramax pickup. If your Duramax has several fueling and performance upgrades or if you're looking for improved filtration and enhanced injector life, we recommend you install one of the FASS Titanium Signature Series pumps.
