I have a 67 camaro. It has a large fuel cell in the trunk with an electronic fuel pump. I am not sure on the brand of fuel cell. I want to buy an Autometer C2 fuel level guage, I think it is 0-90ohms, but I am not sure if this gauge would work with my current sending unit. Can anyone explain to me how I would be able to tell if my sending unit will work with this gauge? Thank you.
