Description
Enhance the fuel delivery to your 2007.5-2010 GM 6.6L Duramax engine with the Fleece FPE-34789 PowerFlo Lift Pump. The Fleece PowerFlo Lift Pump Series functions as a replacement style lift pump that installs directly in your fuel tank. This direct replacement can support up to 800HP! Because this pump installs in your tank like an OE style pump, it retains all your factory components like your water-in-fuel sensor, factory fuel heater, fuel lines, and it installs in less time than other lift pumps. No cutting holes, no noisy frame mounted pumps, and no quarter-tank issues thanks to the active fill bucket design.
Dual Gerotor Design:
Two is always better than one. The PowerFlo Lift Pump has two OEM quality gerotor pumps to increase flow and reliability over the factory pump. The Dual Pump design is capable of supporting up to 800 HP and supports the use of dual CP3 pump configurations.
Seamless Integration:
The active fill bucket eliminates the need to install a fuel tank sump, draw straw, or additional air filtration. This also eliminates the 1/4 tank issues that are common with the other high-flow lift pumps on the market. For those with aftermarket lines or filtration, the pump outlet and return is threaded to accept a -8 O-ring fitting (3/4"-16 thread) so you can customize your fuel system.
Features:
- Silent Operation
- Drop-In Lift Pump
- Supports 800 RWHP
- No Sump or Draw Straw Needed
- Lifetime Warranty

Have every mod under the sun done to my LMM except a lift pump and drug my feet with WOT problems until I came across the Fleece in-tank lift pump. After installing no more WOT problems and it finally has some gusto! Easy installation and works beautifully. The pump is super quiet which is also nice. Highly recommend!

I bought the pump 11/3/2021 got the pump 11/4/2021 was installed that night. I used all original lines. Only 3 wires to hook up. No cutting, soldering, splicing no nothing not one modification to install. I can’t emphasize enough how easy it was to install. Only thing was tank had to come down but it was down and out with 2 guys in 20 minutes. The reason I did the lift pump was issue with truck starting after I ran it for a hour or so I would have to pump fuel back up with primer. I chased a vacuum leak for months until I broke down and did the lift pump. Well with it installed truck stars up immediately and has not given a issue. Last let me say the pump is not quiet it is silent. My issue with the other pumps was the hum and driving down the road they are loud even with the radio on. You get what you pay for. This is worth every penny. Oh I almost forgot LIFETIME WARRANTY!!!!!!!!

Had the typical "lack of fuel pressure" from my Duramax under load. Replaced the stock fuel pump with this high volume, Problem Solved.
