Fuel Pressure Regulator

I am adding an electric fuel pump to an 8BA and have read that I will need a regulator to get the delivered fuel pressure down to 2-3 psi. What's the most practical solution? This is not cosmetic. I am interested in performance and value.

Get yourself an inline fuel pressure regulator at your local parts house. 1 1/2 to 2 pounds is plenty. I wouldn't even go as high as 3# on the stock carb. The cheap regulators aren't particularly accurate. You might want to check whatever you buy with a mechanical gauge to verify the pressure.

I was using Holley's cheapy reg (deadhead), it is what it is, cheap!

I went with Aeromotive bypass style (haven't fired it up yet) but it's a LOT more money.

While I can only afford the cheapy regulator, I rely on a pressure gauge to tell me what pressure gets to the fuel block. Mine likes 2#.

You can easily improve the performance of the "deadhead" style reg's by using a filter after the reg that has a bypass back to the tank (this also assumes that you have a tap to dum back to the tank). Mid-80's carbureted Chrysler 2.2 engines used these. By passing a small but constant amount of fuel back to the tank, the reg never truly deadheads, and can maintain pressure better. I'm considering adding a nozzle to the filler pipe on my '52 to allow use of one.
