Description

The FASS DMAX-7001 Dura-Max Flow Enhancer Fuel Pump for your 2001-2010 GM 6.6L Duramax is the perfect option for stock trucks and budget minded enthusiasts. Duramax diesel engines do not come with a factory lift pump, this is why Duramax owners see such excellent performance after installing a fuel lift pump.

When the CP3 injection pump pulls fuel under 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 reducing the amount of work your factory injection pump has to perform. This extends its expected life and improves performance gains. Since the D-Max Flow Enhancer is a "pusher" pump, all fuel is placed under pressure, helping prevent the introduction of air and vapor.

Features:
  • Easy Installation
  • Improves Fuel Flow 
  • 8 PSI Fuel Pressure 
  • Increases Performance
  • Delivers Fuel Under Pressure 
  • Reduces Factory CP3 Workload

I haven't had any problems after replacing the last fuse. The pump does its job and I haven't had to prime the filter once since pump install. Fixing to change the supplied filter and the cat filter that I also converted to. Thanks again xdp!
