Three gaskets in the Racor?

1. O-ring on shaft of T-handle
2. Large O-ring under the metal top
3. O-ring between glass bowl and metal body.

Checked 1 and 2 and replaced both. If 3 was out or leaking would that be why the top of the Racor is empy and the bottom glass bowl stays full?

The lines are right, they are cut, run and tie wrapped so they can't be swapped.

Went to the tank and checked pickup, return line and vent line. Blew clearly into the pickup at the tank and got bubbles. Put pickup line back on and blew from tank selector valve (two tanks but I'm only working on one) and got bubbles again into the tank. Blew from selector line out on the valve into the Racor and got clear.
