Thanks, Donnie. I may have located the problem. The pressure regulator leaks fuel from the vacuum hose connection when the system is under pressure. While it is running, if you remove the vacuum hose, fuel will constantly drip out. If the engine is stopped, it will drip until the pressure is low. This raw fuel dripping into the intake path when the engine is off may be "flooding" the engine and the reduced pressure in the fuel rail may cause some prblems. By the way, where is the check valve located?
