Fuel pressure regulator, Where to locate in engine bay Options

[North Coast Jim]

My new 2056 engine running 44IDFs has now about a 40 miles on it. So cool to have this car back on the road after 25 years. Runs way to rich with a 160 main, 175 air correction, 60 Idle jets and a 36mm venturi. Continue to have a problem with popping through the carburetor at partial throttle. Fuel pump is the Carter rotary with inline filter along with their SS lines through the tunnel purchased from Tangerine Racing. Engine builder wants me to install a fuel pressure regulator to eliminate this as a variable. The jetting exercise can come afterward. I bought an Italian made "Petrol King" diaphram regulator with single outet. Will hook up serially the pump/ filter/ regulator / guage than "T" off to the two carbs. I'd like to hard mount this device but where ?? To the body or to the engine ?? I'm sure this has been done before. Any suggestions. Pics would also help. Thanks World

What's the pressure on your fuel pump?

When i had my carbed 2056, the CB rotary pump put out 3.5psi, there was no need for a pressure regulator.

If your pressure is too high (from the sound of it), you need to install it between the pump and the first carb.
I would install it as close to the pump as possible.

Also of note, you might want to put the filter behind the regulator or before the pump unless the filter is designed for high pressure.
