Hello. I have a max flow an 88ci 4500psi tank and reg combo, and just purchased a dye tank cover for the tank. I order the 88ci 4500psi size obviously. When I opend the package containing the tank cover, i could tell by looking at it that it wan't going to fit my tank. My tank is a bit thinner and longer than most nitro tanks i see today. (I did manage to get most of my tank covered, but at the top there is about two inches exposed still.) I'm not sure why. Are there special tank covers for the tank I have? I need some help here. Thanks for looking.
