Description
Overview
The FASS DMAX7001 Dura-Max Diesel Fuel System Flow Enhancer is engineered specifically for the 2001-2010 GM Duramax 6.6L, delivering a dependable, pressurized fuel supply where the factory left one out. Duramax diesel engines don’t come with a dedicated lift pump from the factory, which is exactly why owners see such notable performance and economy gains after adding an aftermarket diesel fuel system. Part of the proven D-Max Series, this Flow Enhancer is built to support your stock injection setup and get more consistent, cleaner fuel to your engine.
When the factory CP3 injection system pulls fuel under a vacuum, it can introduce air and vapor into the fuel stream — a condition that can ultimately lead to injector failure. Because the D-Max Flow Enhancer is a pusher-style system, all fuel is placed under pressure, helping prevent the introduction of air and vapor before it ever reaches your injection components.
Key Benefits
The D-Max Flow Enhancer is designed to provide your Duramax engine with a constant 8 PSI of fuel pressure (rated 8-10 PSI), directly aiding the injection system by reducing the amount of work your factory CP3 has to perform. The result is an injection system that isn’t fighting for fuel, an extended expected service life for those factory components, and improved performance gains when you’re running aftermarket tuning products.

Who It’s For
The D-Max is well designed for stock trucks and budget-minded shoppers who want the protection and consistency of a pressurized fuel supply without stepping up to a larger system. If your truck is running a mostly factory fueling setup, the DMAX7001 is a smart, targeted upgrade. For owners who have several fueling upgrades, or who are looking for improved filtration and all the benefits that come with the FASS lineup, the Titanium Series systems are the suggested step up.
Fitment
The FASS DMAX7001 is designed for the 2001-2010 GM Duramax 6.6L, fitting Duramax Truck and SUV applications. With its stock-application design and D-Max Series engineering, it’s a purpose-built match for owners looking to protect their investment and get the most from their diesel.
