TPI to Carb Swap

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..

Re: TPI to Carb Swap

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.

Re: TPI to Carb Swap

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