I used to have a buddy at the local fire station that would get me a fill, if I needed one quick....
Actually there is controversy now that debates the water cooling method while tank filling. The debate is that the fill whips are getting wet, and that forces a few drops of water into the tank, causing rust/oxidation to form inside the tank. They feel it would just be better to fill the tanks more slowly with no water.
At the rate some of these shops fill the tanks, they should be using ice water!!!!!
I have hauled a few tanks in my Crossfire, so I guess it is still OK to post this on this forum?!?!?
