    Also my tank is 7" in diameter.

    I am still not sure how much air these things hold!

    I am still not sure if my tank is plus rated, wouldn't that change things?

    It's a really good thing that something as critically important for survival is so easy to understand. lol

    Look closely for another stamp.

    Is there a plus sign (+) after the 2400?
    Well, you asked.
    Why have to remember a tank factor, when all the other info you need is right in front of you?
    Also, by the continual rounding off of fractions, you lose accuracy. For example, 2640/85 = 3.1, not 3 or 3.2.

    SO the 09 * 04 + stamp is below the rusty stamp (hydro stamp) it is under the paint.

    The rusty stamp says 1 03/04 19.

    No but there is another plus sign over underneath the rusty (hydro?) stamp that says 09 * 04 +

    @CaveSloth
    Perhaps you should post a photo of the tank markings, to avoid confusion.
