Default Critique my 700rwhp setup

Sumped tank
(2) -8an lines to (2) inline Walbro 255s (1 filter before each, 1 big one after the y block??)
Hobbs switch for one of the pumps
Both lines to y block
-8an to FAST rails
60lbers
Aeromotive return fpr
-6an return to tank

Sound good? Any ideas?

Actually I'm thinking -6an to the pumps should be sufficient?

sounds good man. I would say you should be good for 800ish rwhp. I would also say with bigger injectors you would be good for a little more

i would go the 2 -6 lines to the y block. I have basically the same setup except the dual in tank pumps instead of inline. You don't need the hobb switch if you are doing the full fuel system. I didn't do one, plus 1 less thing to worry about failing.

Why is the Hobbs switch not needed? I heard it saves a pump/keeps temps down.

I'm sure it saves the pump from not running all the time, i was just saying with the fuel system like you are doing, you don't HAVE to run a hobb switch. If you run stock lines you usually can't run both pumps all the time due to the lines themselves can't take the volume. I opted not to do a hobb switch for chance it would fail and not let the second pump come on.

Either way will be fine, i was just throwing in my .02 that's all man.

Gotcha that's what I'll do. Thanks!
