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

I'll pile on the "venturis are too large" argument. They might be the choice for a race car that lives above 4000 rpm all day.

Popping through the carbs is either a lean condition or incorrect ignition timing.

All this is not to say you don't have the wrong fuel pressure. Check it with a fuel pressure gauge. If you need one, I have a nice one that also functions as a T for $40 without fittings.

Also there are two types of fuel pressure regulators, bypass and blocking. Bypass is what you use when you make a loop with a return line, where the regulator goes after the loop, and to the return line. Blocking is used before the carbs.

EDITED: talking about stuff I don't know any more, sorry...
