since I have it running now I am fixing the little stuff and getting a working gas gauge on a car I know now get horrible mileage(but not sure how bad) is important. For some reason it has never read above 1/2 a tank, but it has gone down to almost 0 when it was almost out. I think the sender should be showing 145 ohms when full but I read 157 at the tank and 178 at the dash. I thought maybe the ground to the sender needed to be cleaned up. I could not find the factory ground location so I thought I would just cut it inside the trunk and ground it to the battery right there. I found the wire that measures 157 with the sender wire and figured that with that ground wire cut that it would not read an impedance but it still reads 157 even with the ground cut. Is there a ground for the tank by chance and a way the sender is grounding out inside possibly? It doesn't make any sense to me
