1 of the 3 ports on the bottom of the throttle body connects to the air tub to the PS pump. The other two are for coolant to the throttle body. Don't mix 'em up.
The fuel pressure regulator is on the timing belt side of the motor and should have a small dedicated vacuum line to the intake manifold - nothing else should be attached to that line. What you are talking about seems to be on the transmission side of the motor...So I found the hose that connects to the air tube. I had connected it to the fitting that is right above the air tube. This appears to go to/or under the fuel pressure regulator? It's on the fuel rail where the fuel line comes in from the fuel filter.. So my next question is, what hose connects to this fitting? It seems I am missing something.
