I’ve had this happen both on baseline Camrys and Corollas. Interestingly it doesn’t seem to happen on higher end models. Basically it’ll click before it’s full. If you go inside to check the gauge it still shows low, so then you add more and it clicks again. Check gauge again and still isn’t on the F line, pump more, check again, still hasn’t moved. Then you go off and drive away and the gauge climbs while you’re driving. I don’t get it, super strange, but I’ve definitely had it happen to me.
