concerning my 3.1 v6,

first off: there's a vacuum link connecting the fuel pressure regulator and the AIR system and it runs to the throttle. i took off the AIR pump today and disconnected the vacuum hose, and gasoline flowed out. turning the air pump upside down led to gasoline pouring out. i take it my fuel pressure regulator is garbage? there's vapor within the fuel rail too.

also, where the hell can i find an egr flex hose? mines got a large crack in it.
