GM Duramax 6.6L
Diesel Fuel Pump
Duramax diesel engines do not come with a factory lift pump. Durramax owners will see an increase in performance and fuel economy gains with the installation of the DMAX-7001 pump.
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 Flow Enhancer has been designed to provide your Duramax engine with a constant 8 PSI fuel pressure, which will aid the injection system and
decrease the work you factory injection pump has to do. Fuel is placedunder pressure, helping prevent the introduction of air and vapor.
Extends injector pump life. Improves Performance of aftermarket
tuning products. Made for the budget minded shopper.
