ss60 air compressor

Sure it’s not fuel? Looks awfully wet on the fuel pump. There’s a weep hole in the bottom of it. Maybe the seal/gasket from pump to compressor. I don’t remember for sure, but think it’s a paper gasket. According to Detroit, you can put a wire into the weep hole, crank engine, and if you feel the wire vibrating, its bad. You’ll have to confirm all that. I’ve never done it, just changed the fuel pump when I replaced my compressor. New one seeped for a few days around the gaskets, before sealing up.

 

I would clean that up as best as possible. Brake cleaner and rages or something. Set the idle at the fastest speed and watch. Like to know what the problem really is before I go swapping stuff.
