Unloader valve plumbing on Dayton 3z960

by John Fields

I bought an old air compressor that was used at a service station years ago. The compressor had been replaced with a Dayton 3z960 pump, the small tubing was missing at the unloader valve.


There is a 1/8"tubing line from the 1st stage head valve to the second stage head valve, I presume this is the unloader valve.

There is a connection from the unloader valve that is not connected but has a broken off short piece of plastic tubing in it, where did this line connect to?

Sorry, too many unknowns.

Can you get some pix showing context?

You'll need to start a new thread, reference this one, post pix, and Bill will pull them together.
