FASS Duramax Flow Enhancer - 2011-2012 GM 2500/3500 6.6L Duramax (DMAX-7002)

This is the FASS Duramax Flow Enhancer built for the 2011-2012 GM 2500/3500 6.6L Duramax (DMAX-7002). FASS Fuel Systems part number: DMAX7002.

The Duramax doesn't have a factory lift pump. The CP3 pulls fuel all the way from the tank on its own. The FASS Flow Enhancer is a supplemental lift pump that feeds the CP3 instead of replacing it, taking that suction load off the injection pump and supplying fuel at a steady pressure.

FASS calls it a bolt-on install. It is not a filtration system. If you also want 2 micron filtration, water separation and air removal, look at the Titanium Signature Series for your Duramax. Turn14 lists DMAX-7001 for 2001-2010 trucks and DMAX-7002 for 2011-2012. FASS sells a separate mounting package for each, so call us if you want it quoted with the pump.

Why we like it

• Feeds the CP3 so it isn't pulling fuel from the tank (per FASS)
• Steady supply pressure to the injection pump (per FASS)
• Bolt-on install (per FASS)
• Built in the USA (per FASS)
• Emissions: not CARB exempt. Not legal for road use in California or other states that follow CARB rules on pollution-controlled vehicles

California and CARB states: this part does not have a CARB exemption number, so it is for off-road or racing use on pollution-controlled vehicles in those states.
