Manufacturer Description

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 Inch-16 thread).

Soft!
Color: Peach Fuzz
These socks for dry heels are wonderful. I purchased a balm for my feet and these help it soak in over night. They have a gel liner in the heel which is soft. The first few nights I could. Feel the socks just because I wasn't used to it but after a few wears I can't tell I have them on. Love them and seem to be helping my heels.

Soft heels, here I come!
Color: Blue Haven
⭐️⭐️⭐️⭐️⭐️ I bought these for my 16-year-old daughter, and she loves them. They’re super soft and cozy, and they’ve really helped with dry heels. The moisturizing lining works great, and her feet feel noticeably smoother after wearing them. She even wears them around the house because they’re comfortable, not bulky or slippery. Great quality and a fun little self-care item — definitely a win! I even bought myself and my mom a pair!
