Fleece Performance PowerFlo® In-Tank Fuel Lift Pump – FPE-34790 2007.5–2010 LMM Duramax
The Fleece PowerFlo is the only true in-tank lift pump capable of supporting up to 800 horsepower on the 2007.5–2010 LMM Duramax. It delivers consistent, positive fuel pressure to the CP3 injection pump, reducing strain on the injection system while solving the common low-fuel and aeration issues found with stock pumps.

- Threaded outlet & return – Accepts -8 O-ring fittings (¾"-16) if you want to run aftermarket lines or filters
- Operating pressure: 10–13 psi at idle
- Validated for use with up to 20% biodiesel

Fitment
- 2007.5–2010 Chevrolet Silverado / GMC Sierra 2500HD & 3500HD with the 6.6L LMM Duramax
