What I was getting at, and be a nice guy was, people think that," if I'm running 60 psi ill just make the pump run 100psi and all will be good in the world." and you have lost volume,sometime a lot.
Thank you again for taking the time to post all that.

While you can do this (run a pump harder to provide the same flow/pressure as a smaller pump with a larger line), it is not ideal to do longevity concerns. If an aux pump + OEM fuel pump is not adequately supplying enough fuel for your horsepower goals, I believe that is the time to upgrade the lines while you are upgrading the in-tank unit.
