Wondering if yous can put me on the right path?
I'm trying to figure out what kind of fuel pressure regulator I need to run with my setup, I plan on going with 90lb injectors with duel pumps in the stock bucket in tank, it's an 07 suburban 5.3 full exhaust stage 3 cam whipple supercharger currently has the stock fuel pump regulator in the tank no return line

 

External regulator right by the fuel rail would be a good idea. Even going to a return fuel system would be nice.

 

FFDP, I figured I'd dump the return right back into the bucket and from what I read run my feed to the fuel rail and put the regulator on the back end of the fuel rail this should be good right? Also should I be using a vacuum dependent style regulator? Also thanks for the reply
