I would have thought it would have had a ASME (permanatly mounted) tank and not a DOT (portable) tank. I guess I still learn something every day
. I do not see any reall problem with puting in a smalller tank except the fact that it will have to be refilled sooner. Just make sure it is securely fastend.
