Good quality fuel pump ? or is there any Diffe

Pep boys here in Tampa has a Carter for a 340. That is what I am running, however, I don't know if they carry one for the slant (225) not sure of interchange, ect. Sorry to be vague. I do know my friend w/ a 340 got a few of the ones from advance, and they were all junk. Seems since they merged (from Discount) things fell apart.
