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.
The D-Max is well designed for stock trucks and 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.
