Bartamos- I'm talking about the '50 truck. The flare fittings I will install of course without any additional product, but I'm very leery of putting a tank in the cab without anything on the screws... these days I have to wonder whether the replacement screws are as well made as the ones that the tank came with- they may not be.
Jim & Ray- thanks for the info. I like using cork when I can find it.
I installed a tank in our '63 and I swear the thing is venting through the screws. I did not put anything on them.
