    Straps are much better than adhesive. the more the better.

    Ditto what Stan suggests. Place the tank on a stable, non-flexible platform and strap the crap out of it.

    ABYC has specific requirements for mounting aluminum tanks into boats
    I do not have access right now to reference all the requirements but will give you some basics
    1) The tank cannot just sit on a flat surface because if you get water between the bottom of the tank and what it rests on, in the absence of oxygen, you will get corrosion
    You must either set the tank on strips of plastic or on solid plastic. This plastic must be permanently adhered with a marine adhesive to keep water off the aluminum
    2) Any straps going around the tank require the same treatment, ie glued strips to the tank before the straps go around
    3) All fittings for the tank have to be either aluminum or stainless, never brass/copper
    4)I cannot remember if the tank needs to be grounded to the boat.
    5) If you are connecting rubber fuel line the the fittings you require 2 stainless gear hose clamps per joint, same with filler hose. You have to ensure that the worm is stainless as well. Most automotive clamps have a galvanized worm and will rust
    There are also some other stainless clamps that will fill the requirement especially for the larger filler hose
