Hello all, first off i did a search of the site and could not find the answer to my question. So , i have installed a new auto meter fuel gauge 0-90ohm in my 66. I just installed a new fuel sending unit(orginal style). The tank is near empty with fuel,but the gauge is reading past the full mark. I have checked and rechecked the ground. There is a new ground wire on the sender that i have mounted to the frame. I pulled the ground wire and it still reads full. Any help on this is appreciated. Thanks.
