So brand new gas gauge and a new sending unit. It all worked fine out of the dash with ground wire hooked up. Unhook the wire to the sending unit and it showed full then I grounded the wire and it showed empty. One caveat, to make it work correctly I had to hook the sending unit to the full side of the fuel gauge in the ignition to empty side. Bad news, after installing back into dash nothing reads on guage. Hope someone knows what I need to change. Thanks
