Hi Terry, thank you for the post, it prompted me to have a good look at my fuel shut off valve. It has a weep, but I’m not sure if I should venture into pulling it apart or not. Hoping the photos I’ve posted help you. Good luck with the restoration.

I'll have to look through my old documents, but I recall it being a ball valve, maybe a Weatherhead, with an extension on the lever that has a wee ball on it for the shut-off rod that goes over to the left side of the cockpit. There is also a service bulletin suggesting an elbow with a ball valve and a drain line be installed to sump the tank.

Steve's photos show a round, Curtis quick drain installed in the tank sump, and also the lever extension and shut-off rod.

Thanks Andy and Steve.  Your comments and pictures clear things up.
