I knew I'd get at least a fart joke out of that Ha. High pressure tanks like O2 and C02 have a double valve on the tank that should be either opened all of the way or closed all of the way or they will leak a little, Just checking cause it can save gas.
And always open them slow to not damage the regulator.
Yea trying to tell that to my son and he is learning but hard on equipment for sure. I always purge the tank when done welding same with any high pressure system all on and off and purge.
Thanks BP good info.
What did you find to match the package tray in the Impala and not sure what you are doing but I am curious.
