I've had a tank or two wind up riding sideways from vibration and pouring fuel before I noticed. Yer tank would have to be REAL LOOSE to move out of the way fast enough to save the sack. It would only move a few inches anyway and not far enough to do much good. If yer gonna Smack the sack there's not much you can do about it except grit yer teeth REAL HARD and cuss a lot, LOL.
