The PowerFlo lift pump is the latest OEM replacement performance lift pump from the diesel experts at Fleece Performance. The PowerFlo is the only in-tank lift pump capable of supporting up to 800 hp! The LML when delivered from the factory relies on vacuum from the CP4 to draw fuel from the tank, this puts extra stress on the injection pump and can lead to premature failure. The PowerFlo lift pump provides positive fuel pressure to the CP4, decreasing strain on the injection pump and supporting up to 800 hp. FEATURES Direct OEM In-Tank Replacement: The PowerFlo Lift Pump retains the factory fuel lines and installs in less than half the time of other high flow lift pumps. OEM Quality - Dual Gerotor: Two is always better than one, and the PowerFlo delivers with two OEM quality gerotor pumps, increasing flow capacity and increased reliability over the factory pump. Capable of supporting up to 800 hp, including dual CP3 pump configurations. Seamless Integration: The active fill bucket eliminates the need for tank sumps, draw straws, additional air filtration, and the 1/4 tank issues typically encountered when seeking a higher flow lift pump to meet your engine's need. Aftermarket Capable: Want the benefits of the in-tank pump but need to run your own fuel lines or aftermarket filters? The pump outlet and return is threaded to accept a -8 O-ring fitting (3/4"-16 thread).

Comfortable and Slick
Color: Grey, Size: X-Large
The track suit has been my tai chi workout go to. The fabric is light and non constrictive so I can move effortlessly. The material is soft and feels nice. Does not get too wrinkly when folded. The color is nice. Top fits nicely, true to size (6’ and 190 lbs). The bottoms are a bit baggy though but my bum is flat, so can complain. I think next time I would purchase separate pieces and go with XL top and L bottom. Perhaps mix the colors too so I don’t look like an orderly on break! I will caution on wearing this type of material over spandex or slippery underwear. I was walking my three large dogs and they got tangled and the leash snagged and pulled down my pants exposing my underwear to the world. Luckily, I had clean undies with no rips, although no one was around the trail we were on! This is my first Coofandy purchase and I would definitely purchase again.
