Today I replaced the output stage on the air compressor given to me by my coworker Brian. Beyond a small handful of brass fittings I replaced the regulator, added a filter, and adjusted the automatic shutoff. It now turns on at ~80 psi and shuts off at just over 100 psi, and everything I replaced or moved appears to be operating smoothly. There is a leak in the upper compression fitting on the line between the pump and tank (seen on the right here) which loses about 2 psi per minute, so I’ll probably replace that with a flexible line. The hard shutoff which is built into the manifold also leaks very slightly, but as I don’t want to spend time finding a replacement I’ll let it be.
With the purchase of a rather nice Goodyear hose, blower handle and tips, brass quick disconnects, and a tire inflator from Harbor Freight, I think I’ve got everything for it that I need. It would be nice if it held pressure, but as I don’t intend to store it pressurized I’m not too concerned.
