i'm putting together my first carb setup. i know to run the feed line to the pressure regulator and then to the carb. but i don't know where to hook the return line up to.

i'm running a standard holley pressure regulator. p/n #12-803. it has three pots. two are stamped, "out" and one is stamped, "in". The instructions say to run the feed line to the "in" port. And run the out ports to each carb if you're running a dual carbs. and if you are running one carb to plug the extra "out" port.

i want to know where if i plug the extra port, where do i run the return line to?

 

That's a deadhead regulator, you can't use it with a stock pump.

 

i don't have a stock one. i have an aeromotive ss pump. http://aeromotiveinc.com/products-pa...l-pump-38-npt/

 

do i have to use one with a return on the regulator?

 

Not with that Aeromotive pump, but there are advantages to doing so.

 

so do you think if i got something like this would that work?

That should work.

 

i would recommend using a bypass type regulator.

 

isn't that what the one is i put up the link to?

 

The 12-803BP is, yes.
