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).

My absolute favorite boxers ever
Size: XX-Large, Color: White
I'm not a man, but I'm a nonbinary person with a big bottom and have tried many quality boxer brands over the years (including the unisex brands). These are my absolute favorite brand of boxers. They're super comfortable. It's taking me a while because I just keep forgetting to stock up but they are replacing all of my other boxers.

Good fitting support !
Size: Medium, Color: White
Just what the man needed. Very good contoured support. No jostling. Not a loose potato sack after an hour of wearing this. Highly recommended. Compare? Hanes, for example. Even the Jockey brand. Put those on, they're tight fitting, seemingly supportive. But they're not. They aren't contoured to fit. That's the whole idea. Contoured, to fit. And stay fitted. The trunk type, just like this wirarpa, and in half an hour it's loose loose loose fitting. A potato sack. No support. No support at all. That's not what a trunk brief is supposed to do. It's supposed to support, give comfort and confidence, stay in place feeling. Assuredness. And this wirarpa Mens Trunk does the job ! Wash and wear and wash and wear. Stays in shape, never gets stretched out and loose, for the fit.
