FASS DMAX7002 DIESEL FUEL SYSTEM FLOW ENHANCER FOR 2011–2016 GM 6.6L DURAMAX

Product Description

Overview: The FASS DMAX7002 Dura-Max Flow Enhancer maintains a consistent ~8 PSI fuel pressure to reduce CP4/CP3 workload, improve fuel delivery under pressure (not vacuum), and help curb aeration that can lead to injector wear—an ideal, budget-minded upgrade for stock and lightly-modified LML Duramax trucks.

Fitment: 2011–2016 Chevrolet Silverado / GMC Sierra 2500HD & 3500HD with 6.6L Duramax LML.

• Constant pusher-pump pressure helps prevent air/vapor intrusion.
• Supports better throttle response and smoother fueling.
• Simple, clean-mount installation.

FAQs

Do I still need a full lift-pump system if I add the DMAX7002?

The DMAX7002 is a great reliability and drivability upgrade for stock or lightly-tuned LMLs. For heavy fueling mods or when you want finer filtration/air separation, step up to a Titanium Signature Series system (see links above).

What fuel pressure does this unit supply?

It’s designed as a pusher-style flow enhancer targeting roughly 8 PSI at the inlet to reduce pump vacuum and aeration concerns.

Will it help CP4 longevity?

By supplying positive pressure to the injection pump, it reduces the pump’s workload and the chance of air/vapor ingestion—both helpful for component life.

Is there a noticeable performance change?

Most drivers report improved throttle response and more consistent fueling, especially under load and with tuning.
