Fuel gauge. Again.

I have run into this a few times on different cars. It was the ground, the gage, and the float sticking. 1.I grounded both ends of the ground wire to bare metal. 2.The gage was replaced . 3.The gage was removed and sprayed with WD40 on the moving parts (needle sticking) and cleaned. Used float gage lubricant, water remover called Sea Foam? or whatever I had in the shop. Does it do this when key ignition is turned to both LF and RT sides?
