Description
Eliminate the factory fuel restriction above 3,000 RPM with this affordable upgrade from Fleece Performance for your Common Rail Cummins! The Fleece Performance CP3K is a modified Cummins CP3 designed to eliminate the factory fuel flow restriction that begins at 3,000 RPM. If you have a stock CP3 pump you are losing fuel flow and rail pressure after 3000 RPM, which correlates to lost horsepower when you need it most. This cost effective upgrade will allow you to maintain desired fuel rail pressure through your entire RPM range.Every Fleece Performance CP3 is tested on their in-house engine simulator and pump test stand to simulate real world situations and ensure that each pump is ready to work. Fleece builds their pumps from BRAND NEW CP3's, which means NO CORE CHARGE and NO USED PARTS!

Works well for my set

"Works well for my set up."

Garrett W. (5/5)

CACummins

"For the same price as a new 5. 9 pump, this kit allows you to upgrade to a more common 6. 7 pump in case you have a problem in the future. It comes with 3/8 and 1/2” supply fittings so you can use the factory line or if you have a FASS/Airdog. Unfortunately, the factory line is metric and the 3/8 hose that’s supplied is too loose and needs to be cranked way down to prevent leaks. I wasn’t having a fueling problem over 3K rpm, but it’s nice to know I can push the horsepower ceiling a little bit. I hope Fleece will put the high pressure line for sale on their website because if you have a problem with it in the future, you’re SOL ."

Q&A

How much horsepower can this pump handle? I want to get my truck in the 600-700hp range.
This pump is good to around 650hp depending on tuning and supporting mods.
Will this product support 40% over injectors?
That would be getting close to its limitations, depending on what you are using the truck for, I might suggest jumping to the 10mm/750 pump.
Will this work with stock injectors? My truck is a 2006 5.9 cummins
It would work great with stock injectors! -Sands
I was wondering what % over the cp3k is exactly? Is it similar to a 33% over industrial injection pump??
The CP3K is a stock output pump with mods to reduce the fuel restriction above 3k rpm. The PowerFlo 750 is Fleece's higher output stroker pump. SA
