First off,Thanks for the FYI on the fuel gauge,and warning light. So far though the gauge and light have been working properly. I get a reciept and double check mileage every fill up. But here is something I found out through talking about it to my father in law,Who delivered gasoline and diesel for years. He said that. A stations fuel pumps will run off by quite a bit in hot weather. That even if they calibrate them in the morning. By afternoon they can be back off again. It has something to do with the cold fuel from underground hitting the hot pump and expanding. He strongly recomends to fuel up in the early morning if at all possible. Something to think about. I know I`ll check it out and see what happens. PS when I filled up that day it was 90+ degrees. Thanks again for the input.
