u should only have 1 fuel pressure regulator the other one is like a check valve to hold fuel pressure on start up from what i understand. i dont even have that one on my car any more. did the car just start doing this or did u buy it this way? if u bought it this way it may have a stronger fuel pump and causing it to run rich u need to put a fuel pressure guage on it and see if the fuel pressure is higher. u may have a blockage in the line somewhere in the return. not likely but if u ran something over u may have crimped a fuel return line.
