The fuel system is under high pressure so whenever the system is opened let the pressure bleed off gradually.

I doubt the regulator is bad, the fuel pressure regulator is after the injectors in the return stream to the tank, more likely it is the fuel pump.

As far as I know without checking it personally it sounds like it could be one of three things (in order from easiest to hardest). Clogged air filter, worn timing chain, leaking head gasket. To check for the third go to Auto Zone and get them to do a compression check, its free. I can't remember off hand but if the 93 has a TPS (throttle position sensor) that could also cause an irratic idle.

another engineers wet dream. think of it this way . what is normally in the intake when the engine is running.. answer vacume, hence the regulator gets its vacume without a hose connected to it as its already in a full time vacume chamber.no hose required . ps be carefull to seat the regulator and o rings securely into the housing befor you reattach the secureing metal clip.
good luck chris

If you have fuel on the vacuum side of the reg, that means the reg is leaking,causing a variaty of drivabiliy problems. Replacing this reg is very straight forward. Just add a little lube to the O-ring on the reg before installation. Good luck.

Was there a hose on the old one? If not, you don't have one. It is most likely your fuel pump if you are not getting fuel.
