DOT-E Tanks changed to 5 year hydro?

[Spartan X]

I was told that tanks classified with a DOT-E and that were Carbon wrapped, were to be upgraded to a 5 year hydro. My Local shop told me this. Were can I get documentation to have it on paper so when I meet a nother fill station and they do not know this?

This actually happened a while back, read this (http://www.pbnation.com/showthread.php?s=&threadid=60562) thread at PBNation for more info.

Make sure you read the part about July, 2001. If you have a DOT-E tank manufactured or tested in June 2001 or earlier, it is not a 5-year tank until it's tested.

"Cylinders manufactured or tested after July 1, 2001 must be re-inspected and hydrostatically retested at least once every 5 years."
