2003 safari Cheetah leak

[bkbeagle]

Hello all Newbie to the forum here.

Had generator oil leak (ONAN 7500) that turned out to be a bad seal on filter. Got it fixed and thought all was fine until I checked the next day and found that I still found evidence of leak. Confirmed that additional leask is not coming from generator but coming from here (see attached picture).

I apologize for lack of mechanical knowledge so will try to explain the best that I can. The leak seems to be coming from this saucer looking part with a clamp around the middle of it with an adjustable nut/bolt (there are two of these saucers). The part is located just adjacent to the generator (front of coach) just below where the steering wheel/column and the brake and gas pedal. They both have metal lines presumably leading in and out of each saucer.

can anyone tell me what these things are? Just need a brief explanation so that I can explain to service center and make sure they can handle fixing.

Again I apologize for lack of mechanical knowledge. Any help would be appreciated.
