I *CAN'T* fill my tank up. Try as I might, the pump shuts off and I can see the fuel just below the filler, but my gauge reports I'm only at ¾ of a tank and it seems to be getting worse. When I first bought the car, I noticed I could only get it to 7/8ths, but now it's stopping at ¾. Is there a TSB on this or does anyone have any ideas? Thanks!
