I had my original sending unit replaced about 3 years ago because I had needle bounce when driving. Everything was fine, at least I thought, until today. I decided to drive my truck around today running as much of the gas out currently in the tank out without running out. I started at 1/2 tank and when I filled it after running around and doing errands ( a total of about 50 miles) the needle was registering at just about 1/8th tank. Went to "fill" my tank and I only had to put 8 1/2 gallons in. I know this is a 15 gallon tank. So if the guage registered 1/8th above empty, shouldn't I have had to put at least 12-13 gallons in my tank before it registered full? Because of how low the gas fill inlet is, I always get some splash back. I was manually holding the trigger and it splashed back. I waited about 15 seconds until things settled and then started pumping again at low volume and again got splash back. I do not!!!! want to take this someplace again and have the tank dropped again. This would explain how I can drive 20 miles and burn over 1/4 tank gas. The gauge is not registering. Is there anyway to calibrate the gas gauge?
