Well, time for an update.

No it was not a Shell station; it was Hess or Mobile.

I did hear about the gas problem in the news but the funny thing is that I have the reverse effect. My tank does not appear to still have gas, but show empty when I have gas.

I just refilled with a fresh tank and I am getting the same effect.

Guess I will have to drop the tank and replace the sender, ick.
