If a new stock CP3 is capable of handling 600HP by all accounts, is the lift pump really needed?
A stock CP3 seems to have plenty of "suction", for lack of a better technical term, on pre LML applications.
I understand that the lift pump also provides some additional filtration, but is one really needed for mild 100-150HP tunes? Or is there a cheaper option for air/water filtration?
A good functioning new CP3 system without a lift pump is theoretically simpler and has less chances to fail, airlock, clog right? I've had failures from my "fixes" on other trucks...
Reliability is everything, as I'll be pulling toys far from home whenever I'm using it. I only plan to own the truck for 2-3 years or ~30K miles. At that point, I'll upgrade.
I definitely appreciate all opinions!
