1970 Swinger 340 sending unit
My aftermarket sender was installed when I bought the car. Didn’t work for crap. I have used a Meter Match successfully with an aftermarket sender.
I built a calibration box with information I have got from several threads on this site. I used it instead of emptying the gas tank because I am fundamentally lazy don’t like crawling under the car if I don’t have to. It seems to be about +/- a gallon or two based on my fill ups.
It works by simulating the resistance of the aftermarket sender at four points used to set up the meter match. I selected the values from the shown graph and chart I stole from another thread. All you need to do is hook it up in place of the fuel tank sender and flip switches while you program the meter match. No fooling with gasoline.
If anyone wants to borrow it, I can send it to you, or you can read my resistor values on the box.
