OK guys, i'm new in here so bear with me.
I did a 305 tpi to 350 (carburated) swap. I am going from the Electronic Fuel Pump, to a regular mechanical fuel pump. First off the car starts and runs but loads up terribly. Do I need to install a fuel pressure regulator to solve this issue? The Electronic one is still in the tank..Unplugged
Thanks for any help..

Remove the intank pump, youre trying to pull through it and its severely limiting your fuel flow. You dont need a regulator. There is a sticky at the top of the Carb forum on how to tun your stock intank pickup into a carb pickup.

or remove the manual pump and put a block off plate on it. then go buy a regulator and use the intank pump.
