According to the Larger and Smaller Weapon Damage Table (http://www.d20srd.org/srd/equipment/weapons.htm#tableLargerAndSmallerWeaponD amage), a tiny weapon that does 1d6 damage, would do 3d8 damage if it were huge. (I am assuming a huge-sized tank, here). So it's reasonable to assume that all-told, an exploding tank will to 12d8 damage to all within a 20' radius. What do you think?

Find an explosive fire trap of a CR appropriate for the encounter, or build one using the guidelines in the DMG. There's your dammage.
