I just walked out to check before I wrote this reply and it’s dry as a bone! And the tank is 3/4 full. I don’t think the valve design is a for sure never seep design. Back then your garage floor was gravel. At least my grand fathers was. Boy I miss that oil gas dirt smell!!

I forgot about the Viton needle seal. Sounds like a great idea. I will try that as well.
I have been trying to stop the seepage ever since I got the car: have rebuilt the valve and carburetor. Carburetor runs fine except for the seepage. And the main shutoff after rebuild works well for a few months, then becomes stiff and seeps. I trust this ball valve with the nylon seals will fix it.
