Need some help identifying where this hose goes

[Scott & Heather]

I've labeled literally everything except this hose. It comes out of the top of the backside of the air compressor. I forgot to mark it and I can't figure out where it's supposed to go... arg. Circled in red.


Second question, my new bendix compressor doesn't have the oil feed port on the bottom side like the old one did. So can I use either one of the small ports on the front? Circled in yellow?

Thanks Cliff. I still can't find where I had the coolant hose from the air compressor go... the only one I didn't label. But I guess I can connect it anywhere to a water jacket area on the bloc right?

Nevermind. Found it this morning. Goes to a coolant nipple on the coolant line in the engine bay.
