I’m not sure what’s going on, I fueled my truck up and drove 150 miles and the gas gage read that it only had a little over a quarter of a tank left. I have a 35 gallon tank and when I filled back up it only took 14 gallons. When I put the gas pump nozzle in the tank it released air pressure, which it has never done before. Also every time I fuel up with a full tank, it will stutter start when I first start it, and that’s the only time it happens. Not sure if it matters but I’m pretty sure it has had some body work done on the drivers side back by the fuel tank but not 100% sure. I got this truck from a dealership and they said the previous owner was a Forman for a grain company. The truck looks great and taken care of. But the door jams driver side don’t have un even gaps and on the rear panel by the tank you can feel half ass bodywork and see a small bolt they used to fasten the body. Regardless everything looks (from what I can tell) normal behind the body work on the inside of the truck. This is my work truck and daily driver that I support my family with so any advice or guidance would be appreciated god bless and thank you for your time.
