Thanks 1QwkSport2.5r,

I only keep my fuel in metal cans because I am old and tend to accidently drop things. Glass jars of ether dropped on concrete shop floors near heater pilot lights is not a good thing. I hate it when it does that.... I will try the Teflon tape... good idea... hadn't thought of that... should work fine. Do you have any information on how long diesel fuel will last if left unopened? I have a gallon of Red Max diesel fuel (metal can) that has never been opened but is about 15 years old. Shaking the can feels like it is still pretty full, so I suspect most of the ether is still in it.
