So with the Carter CRT-M6901 you do NOT need a regulator because it flows 120gph and only has 5.5 to7.5psi? Whereas the Edelbrock Victor series EDL-1712 runs 130gph and has a max of 10psi so you DO need a regulator? A regulator is almost as must $$ as the fuel pump. Wonder where the cutoff is gph or psi?

I seem to be running lean with the rochester Q-Jet I have and it looks like it is fuel delivery not carb setup.
