The Mr Gasket regulators are pure junk and don't last any time at all. I've had a top of the line Holley regulator with all the bells and whistles go bad in a month of use.
You gotta watch out for the specs on these new replacement type fuel pumps. 5-7 psi output was waaay too much for the Holley 1bbl on my 223. I wound up having to discard the regulators altogether and go with an orifice ahead of carb and a bypass fuel line all the way back to the tank. That solved the problem, but you have a much easier fix available to you.
