Fuel Pressure Regulator Choice?

Hello,

I am working on an engine with a 6-cylinder and a Weber 32/36.

Apparently this carb runs real badly with anything over 4PSI. My pump exceeds that and I need to regulate it down.

I have seen the low-cost dial types. I have also seen others. Reasonably priced and reliable would be good.

What type would you recommend and from where?

The vehicle is likely going for sale, so I don't need any Aeromotive stuff or anything.

Thank you, ROB

The small dial type are restrictive but seem to work reasonably well up to around 250 or 300 hp.
