I have a 1999 GMC Yukon SLE. I’ve recently noticed that I appear to be running out of gas at the 1/2 tank mark. When I go to fill it, it seems I really do still have 1/2 a tank of gas (so it doesn’t seem to be just a bad gauge). As long as I keep the tank above 1/2, everything is swell. Anyone got any clues what might be causing this?
Thanks for your help!!
