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. 

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 ¼ 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).

Great quality, a bit frumpy
Just ok. Probably should have returned these as I feel a bit like a grandma when I wear them, So they hang in my closet. Not super flattering but nice quality and fabric. Thickness is perfect. Style just isn’t for me but comfy

Amazing Fit For Tall Senior Slim Person!
Fit Type: 33" Inseam, Size: Medium, Color: Lake Green
I usually wear a size 8 or 10 or medium. But being 5 foot 11 and weigh 145, it’s very hard to find pants that fit. These in medium are great lightweight and long enough that they touch the floor in the back. Being older I have extra weight in my stomach and waist, but the waist is wide and not tight. It fits nice in the back also and the rise is long enough. Great summer pants for our hot weather in Florida. Even if they do pill some, I have a gadget that removes any pilling so not worried about that. I got the medium in the teal color which is not as bright but a nice color.

Pilling
I loved these pants very much when I first purchased them the fit was amazing and the length was even better. Pants are very flattering. I wore them for the first time a few days ago only for a couple hours and pilling happened immediately! I am very annoyed at that fact because I purchased these pants at the end of March and I am not in my return window! I am Not a happy customer at all. Waste of money

Bought again but note the material was different .
Fit Type: 33" Inseam, Size: Medium, Color: White
Love these pants . Good quality. Good material and made well. Bought a second pair but they are lighter weight material which is nice for the summer. Will buy again. First heavier white material did not shrink. Not sure about the most recent material as I haven’t washed them yet. Size true to fit

Perfect linen pants
Absolutely love these pants. They are high quality material and well made. The legs aren’t too wide and the wide waistband with drawstring is very flattering. Perfect transition piece between seasons but are lightweight enough to wear during the heat of the summer. I liked them so well I bought in three other colors.
