Just took a trip this last weekend and when arriving back in town, I went to get gas and the pump would not take my credit card, as their computers were down, or something, anyway, I left to go to another station and forgot to replace my cap or shut the door, and when I arrived at the next station I realized I had done this. The interesting thing is, I never got any message on the Christmas tree that there was anything wrong.
I was of the understanding that you would get a message and that the rig would run rough with the filler cap off. Any comments?

Thanks for the info. That clears up my question.
