My ebay feedback on a autometer guage seller

Since the issue is "not as described", if you do nothing, then your also somewhat accountable for the sale, even though you are the buyer. People in sales that are somewhat shady with their sales pitch count on people not complaining, or worse yet, complaining and not finishing it off.
Leave no stone unturned or test it, if it works, put your tail between your legs and do nothing, install it.
I would advise Autometer at the least. It's there rep. at stake here at the end of the day. You might even get a honest answer.

good luck, good hunting!
