    I have an '82 K-10 with a single 16 gallon fuel tank. Whenever the tank comes off of Full, the gauge needle starts to bounce like crazy. Fuel tank and sending unit was replaced because of hole in the tank from rust but the gauge still bounces. Any help or guidance would be appreciated.

    I hope someone knows. I've come to believe the only old Chevys that don't have dancing gas gauges are the ones that are stuck on extra-full.

    It is normal.It is worse on the trucks that have the larger fuel gauge beside the speedo (instead of the tach),as it is much larger and more noticeable,with a larger sweep.

    Most newer vehicle use a damped,or less sensitive fuel gauge,have baffles in the tank,or may run an anti-slosh module to keep the gauge reading steady.The older vehicle didn't utilize this technology,so they bounced around.I'd rather have a bouncing fuel gauge than one that doesn't work or reads inaccurately,like a lot of the newer stuff.
