filled up with gas today and then came home, left again an hour later and the gas guage says i'm already halfway between full and three quarters. it does move some as i drive depending on if the truck is level, which is normal. but it seems to move a little extra or maybe i'm noticing it more since i'm worried i'm losing gas some how. there isn't any evidence of a leak under the truck or around the tank, and i don't smell any gas in the area, but the guage now reads just above three quarters so its definitely dropped more than just the normal movement from being unlevel. is there a way to tell if my float is stuck? what else could be wrong? any and all suggestions much appreciated. wanna get this figured out asap, not rich enough to afford to be losing gas
