I am in the midst of converting my trashed efi to a carb. What I want to do is run lines from the fuel pump to a pressure regulator with return so I can use the carb. However the stock pump is 40 something psi and I only need 6.

my solution was putting a fuel pump meant for a TBI 350 which makes only 12 psi in the fuel tank.

would the lines fit to that pump? And would it bolt into the tank is my question

Or is there a better way to run low fuel pressure for a carb like an in line fuel pump drawing through the stock pump
