Duramax diesel engines do not come with a factory lift pump, this is why Duramax owners see such great performance and economy gains after installing an aftermarket diesel fuel lift pump. When the factory CP3 injection pump pulls fuel under a vacuum it can introduce air and vapor into your fuel, which can lead to injector failure. The D-Max Flow Enhancer has been designed to provide your Duramax engine with a constant 8 PSI fuel pressure, aiding the injection system by reduce the amount of work your factory injection pump has to perform, extending its expected life and improving performance gains from aftermarket tuning products. Since the D-Max Flow Enhancer is a “pusher” pump, all fuel is placed under pressure, helping prevent the introduction of air and vapor.


  • Reduces Factory CP3 Fuel Pump Workload
  • Delivers Fuel Under Pressure
  • Improves Fuel Flow
  • Improves Fuel Delivery and Performance
  • Reduces Air and Vapor in Fuel System
  • Simple Installation

The Duramax Flow Enhancer is designed for stock trucks, if you have or plan to add upgrades to your engine, you may want to purchase the Titanium Series FASS Diesel Fuel System for better filtration and additional features.
