I have an 82 Z28 Camaro that I'm putting a new gas tank in. The new tank has bungs welded in so that I can run an 8 an fuel line to a regulator. The only line on the sending unit I'll be using is one for the return as I'll be using an external fuel pump with a return style system. The electrical part on the old sending unit for the fuel gage works but is a rusty POS and I don't want to use it. My quetion is this. Is the electrical part on a 85-92 sending unit the same amount of ohms and will it operate my fuel gage correctly. I'm thinking of buying a new one but want to make sure it'll work right. Anyone have any experience with this?
