Pressure regulator?

That is interesting most things that i have read states that edelbrock/carter starts having issues above 5.5-6.0 psi.

Is there a way to visually tell if the bowls are over flowing into the carb.

I have noticed in the past after shutting car off and not turning the pump off quite a few seconds before i park, the next time i open the hood i will see what looks like brownish spots on top of the intake right below where the primary butterflies are to the left and right side of the carb. I notice this under both carbs. I guess this could also be due to originally it had aluminum spacers and the carbs would get really hot. Now i have phenolic spacers that i just put on and have not drove it enough to see if the spots reappear.

I found out that this unit is a Barry Grant 170020 fuel log.
