Yesterday the truck was normal and fine but now today I start her up and the fuel gauge stays off. It doesn't move from far low as the peg gets, when the vehicle is turned off. I checked for leaks and there are none, and the engine runs fine I had over 1/8th of a tank left.

it also feels like I hav eto hold the brakes in harder for the same stopping effect?

any idea whats up, could some kids of done something to the truck as a prank or as a criminal intention?
