Deadhead fuel pressure regulator

[K20-Bowtie]

I need some guidance. I have a 72 K-20 with a 350 small block, 1406 Edelbrock carburetor and the stock mechanical fuel pump. The engine is running a little rough at idle and the exhaust smells rich. I tested the fuel pressure and it bounces from 8-9 psi (seems high for a mechanical fuel pump).

I searched the site for guidance on a deadhead fuel pressure regulator and there seems to be conflicting information. Some say a deadhead pressure regulator will damage the mechanical fuel pump.

What’s the best option for a regulator or should I go in a different direction?

Yikes, 8-9psi is too hi for an Edelbrock carb. They need no more than 6psi, or else they start to flood. I can't help on the regulator, I went with an Edelbrock fuel pump to solve that problem.

Thanks - decided to replace with an Edelbrock pump.
