I saw on one thread in the past where the person took the resistor portion of the sending unit off the chevy and put it on the Ferd pick up tube assy. He had to mess with the float rod to give full movement to it. That is the only way to do it. If I remember right the Chevy unit in 0-30 ohms and the ferd is something like 30-90ohms.
You do have to match the sender's resistance to the gauge's full vs empty etc.
I know you believe you understand what you think I said, but I'm not sure that you realize that what you heard is not what I meant!
