I dont know much about the fuel systems of these trucks. but it sounds like the factory one is not working properly.

only if you want an aftermarket or second regulator.

Stocker should be in-tank for your newer truck.

Top of factory spec for this powertrain combo is 73 psi. At 75 psi, that's not enough to be the root cause of the problems you're seeing. Yes, being on the high end of spec could aggravate other richness issues but it is not creating them.
