went to the zone today and fuel pressure at an idle is supposed to be 38-42psi. Haven't got a guage yet but will tonight. I know there isn't hardly any pressure when you put a major load on it. fuel hardly comes out of the fuel rail on the shrader valve. Maybe the boot on the fuel pump might be clogged. They said if the regulator leaks fuel out when you remove the vacuum hose to it, then the regulator is bad. Will try that also.
