Description
Overview
The FASS DMAX7002 Dura-Max Diesel Flow Enhancer is engineered to solve a fundamental challenge on the 2011-2016 GM Duramax 6.6L platform. From the factory, Duramax diesel engines do not come with a dedicated lift system, which means the CP3/CP4 injection system must pull fuel under a vacuum. That vacuum can introduce air and vapor into your fuel supply — a condition that increases wear and can ultimately lead to injector failure. The DMAX7002 addresses this directly by transforming the way fuel is delivered to your engine.
As a member of the FASS D Max Series, this Flow Enhancer is a pusher system, meaning it places all fuel under pressure rather than relying on the injection pump to draw it. By supplying a constant 8 PSI (rated 8-10 PSI), it aids the factory injection system, reduces the amount of work that system has to perform, and helps extend its expected service life.
Key Benefits
Because fuel is delivered under positive pressure, the DMAX7002 helps prevent the introduction of air and vapor into the system — the root cause of many fueling and injector concerns. Duramax owners frequently see notable performance and economy gains after installing an aftermarket fuel system, and the D-Max Flow Enhancer is designed to help unlock the improvements available from aftermarket tuning products.
- Delivers a constant 8 PSI to support the factory CP3/CP4 injection system (rated 8-10 PSI)
- Pusher-style design places all fuel under pressure to help prevent air and vapor
- Helps reduce injection system workload and extend its expected life
- Supports improved performance gains from aftermarket tuning
- Purpose-built for stock applications and budget-minded Duramax owners
- Finished in black and sold as each — part number DMAX7002
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 dedicated pusher system without stepping into a full high-flow setup. If you’re running several fueling upgrades or you’re after improved filtration and the full range of benefits that come with the top-selling Titanium Series, FASS suggests stepping up to a Titanium Series system. For a stock or lightly modified Duramax, however, the DMAX7002 Flow Enhancer is an ideal match.
Fitment
The FASS DMAX7002 Dura-Max Diesel Flow Enhancer is designed for 2011-2016 GM Duramax 6.6L trucks and SUVs. Built specifically for stock applications, it provides the constant fuel pressure your engine was never given from the factory, helping you protect one of the most critical systems on your diesel while supporting cleaner, more consistent fuel delivery.
