Thanks for the post!

I know it's crazy, but your new Belt might be burned up as well.

This is a known problem with this particular motor/pump assembly. My best guess as to why is because the tolerances on the crankshaft and the motor's output Shaft are a little off. If the distance between them is too little or too great, this will obviously affect Belt tension. Also, if they're not aligned properly, the Belt could jump and cause damage.

I would try this again after you drain the tank empty and see if you get the same result.
