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).

Perfect for the price!
Style: 16 Quart Drain Pan
Oil pan has been great. Used it on my 2015 2500 for oil and rear diff changes. No problems at all.

Holds it all and easy to use!
Style: 16 Quart Drain Pan
I bought this oil drain pan when preparing to teach myself how to change my own oil on my Toyota Tundra 1794. Yes. Youtube and I…we be mates. Anyway! This drain pan easily held all of the old nasty oil and made it easy to complete a dirty job in a relatively clean way!

Good
Style: 16 Quart Drain Pan
I have had no issues with leaking. Just double check the o rings are good and in place and you shouldn't either. Although I'll be honest it's pretty over priced. You can go to home depot or o Reilly and find the same exact thing for a third of the price. All the same it's holding my oil just fine.

Not so good - oil splashes all over !!!
Style: 16 Quart Drain Pan
I am SO glad I just saw this pop up in my "purchased" items category...I am not only a Do it yourselfer but I also perform service work for a group of clients as well and I have to say I had a version of this before and threw it out after many years of service due to the fact it started dripping/leaking and I did not want to waste time trying to find it! with that said I purchased this and "What a mistake" every time I change the oil if it does not hit exactly the right angle or area the oil just ricochets off the surface and splashes all over the garage surface (especially when working with 0w20 type oil - thin)...I think this one will be seeing the can soon as well even after only 30-40 uses!!

Rare Small Leaks
Style: 16 Quart Drain Pan
These work well but i have noticed that they leak in small amounts from time to time. Can be a little annoying when transporting used oil or coolant to be recycled.
