Product Details

Product Name: D-Max Flow Enhancer Fuel Pump
Manufacturer: FASS
Fitment Notes: 2001-2014 GM Duramax

The D-Max Pump is modeled around our very successful DDRP Series, utilizing all the benefits associated with the DDRP and adapting them to the Duramax. The D-Max pump is intended for stock to moderately enhanced trucks with a flow rate of approximately 70gph at 10psi.

The Dura-Max Flow Enhancer is modeled around our very successful DDRP series and is now available for the GM Duramax. GM Duramax trucks do not have a stock lift pump which forces the injection pump to "pull" the fuel all the way from the tank, creating a vacuum and constantly introduces more air and vapor into your fuel. The Dura-Max Flow Enhancer creates a postive flow of fuel, "pushing" it to your injection pump, eliminating vacuum and drastically reducing air and vapor in your fuel.

DMAX Series Benefits:

  • Creates "Positive" Fuel Flow
  • Eliminates Suction for the Injection Pump
  • Drastically reduces Air/Vapor in the fuel caused by suction
  • Works in conjunction with the Stock Fuel Filter
  • Easier Start Ups
  • Reduced Maintenance Costs
  • Increased "Positive" Fuel Flow
  • Preset Pressure 8-10 PSI
  • FASS Silencing Technology
  • 4 Year Warranty on Pickup


  • I have a 2016 duramax that I just did the egr and dpf/def delete and am using the ez LYNK tuner that’s 0-180hp. I was wondering if the DMAX flow enhancer fuel pump will be good enough for the tuner I have. No more fuel mods have been and and won’t be in the future. Just need toKnow if it will help enough to be able to run the 180 tune. Thanks.
