Cleaning Gram’s basement I found a stash of these. When I read this thread I thought of you guys that work on gas tanks, lower units, and
headers. These may be useful for pressure testing. I also remember an old thread where one of these valves was soldered into a spark
plug base and used to free up stuck powerheads. I have a bunch of each kind along with many fittings and connectors. I’ll sell them
cheap if there is interest.
