I was getting fills for my PST E7-120 and new Worthington X7-120, and noticed, standing side by side, that the PST looks to be at least one inch taller than the Worthington. Same boot on each. Are the walls thinner in the Worthington?

Thanks for putting the specs together. But the tanks are not the same overall height, or the same shape at the neck area. The PST tank is overall about 1/2 inch taller, and the neck on the Worthington tank is taller. That makes the "body" part of the tank about 1 inch shorter in the Worthington. So if both tanks are the same diameter, and they are the same capacity, then the walls must not be the same thickness. Right?
 
Worthington tank has the higher neck than PST.. It is about double height...
