what wrong with fuel gauge when fuel gauge reading full tank when it has only a half tank ?
had check ground at tank and clean it,also check connections at gauge and there tight.
Find out the fuel gauge connector lug and ground it. The fuel gauge must reads to Full and if the connector lug will be disconnected from the ground the gauge will point to Empty. Replace the fuel tank sending unit.
