Sure Bill,
I removed the fitting with an appropriately sized wrench and plunked the valve into a small container of alcohol. I swirled it around for a few seconds and then removed it and blew it off with an air nozzle. I wiped it with a rag and put it to my lips first one way and then the other to verify proper operation. Finally, I reinstalled it on the pump connected the line and went on to look for my vacuum troubles else where as the system continued to perform intermittently.

I’ll be spending this weekend again with my new best friends a mighty vac and a hand full of golf tees
