Working on 1988 omni with Tbi unit. Just found out that fitting on TBI unit going to EGR valve rusted out and broke off in vacuum line. Anyone have the dimensions for this fitting? I am hoping to somehow remove the fitting and replace it vs. locating an entire replacement TBI unit.

No, not the big pipe. This is the rubber vacuum line going from the throttle body unit itself to the egr valve. The tiny fitting attached to the throttle body unit that the rubber vacuum line attaches to rusted out and broke off. Also a bit concerning why this would even rust in the first place. It looks like the fitting rusted almost completely shut and then broke. Car has idled rough since I bought it a few weeks ago, I'm sure this didn't help.
I can purchase a used throttle body/carb unit for about $75, but if I can simply replace the fitting (assuming I can get it out) that would be much cheaper.

Thank you so much for the info that it is pressed in. I assumed that it was threaded and would have gone nuts trying to unscrew it. Given that the tbi unit was sucking in condensation from the egr and was also sucking in oil into the air cleaner box (from some other vacuum issue, perhaps?), maybe it is simply time to try a scrap yard replacement unit. The existing unit has had a rough life.
