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.
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. Sense the D-Max Flow Enhancers is a pushing pump all fuel is placed under pressure to help prevent introduction of air and vapor, this will also extend the life of your diesel injectors.
The D-Max is well designed for stock or slightly modified trucks or budget minded shoppers, however its suggested that Duramax diesel owners install one of our Titanium Series pumps if you have several fueling upgrades or if you are looking for improved filtration and all the benefits that come with our top selling Titanium Series FASS Diesel Pumps.
