The FASS DMAX-7002 Dura-Max Flow Enhancer Fuel Pump for your 2011-2016 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 great performance and economy gains 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.

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

Excellent product
Installed on a 2016 and it's working perfectly so far. Easy to install. Once I got on the Fass website for instructions, that was the only downside; mine did not come with any.
Just what I was looking for
order 1836978. I was looking for a lift pump for my 2016 lml. Instructions were clear and easy to follow Took about 1 hour to install works great. Its super quiet can only hear it when I'm out side with engine off.
