has anyone had expierance with fuel tank sending units ? I replaced two in my 1995 K3500 6.5 dually stake body dump. 22 gal tank. The unit reads ok until it gets below Half full. then the gage jumps around as if the fuel is sloshing around in the tank. The needle does not hit on empty before the truck runs out of fuel. Is there balles in the tank to prevent this from happening ?
thanks
