TPI to carb

so i have no clue what to do w/ the return fuel line from the original TPI setup. it just pours out gas until i undo the gas cap and release the pressure. right now its just sitting open and obviously theres nowhere for it to go for the carb set-up....well, that i know of...any suggestions?

I used a Mallory 4309 return style regulate when I switched from TPI to carb. It cuts down the pressure for the carb and returns excess fuel to the tank.

You can find them on either Summit or Jegs sites.

I forget what pressure regulator i have on there, but im pretty sure its a mallory. anyways, i have one inlet and 2 outlets on my regulator. obviously one of them goes to the carb...is the other one for the return line?

Yes you have to use a return line to return the excess fuel to the tank. If you have the Mallory regulator the instructions should show you how to route the lines.
