With traditional "plumbing" when we install a pressure regulating valve, we always install a safety relief valve after it on the low side and either pipe it to waste or back to high side. Maybe a return line back to the tank with a regulator on it might help also. You should try and get adjustable regulators, use fittings that can withstand the pressure and set them for whatever pressure (or range) your carb requires. The safety valve is set to open if the regulator fails. Sorry for not specifically addressing your problem but maybe this is of some help.

Went to the local AutoZone store and got a fuel pressure regulator. After installing the regulator the engine is running better than it ever has. However, after about a half hour of driving around the regulator is now leaking and spraying fuel all over the engine. It is amazing that it didn't catch fire. I would like to eliminate the pressure regulator. My question is; is there some type of fuel pump failure that would cause the fuel pump to put out too high of a pressure? In other words, will replacing the fuel pump solve the problem? Also, the engine is a Poly with a Chris Nelson cam and Eddelbrock 600 CFM Performer carburetor (1406). Does the poly take a different fuel pump than an LA engine? What is the correct pressure for a Performer carb?
