Has anyone put in an external fuel gauge outside of the gauge cluster? I am interested in the wiring for this. My sending unit on the fuel tank has two wire connections.
I used a Stewart Warner p/n: 82342 Electric Fuel Gauge, which is correct for our OEM 73/10 ohms sender....... One wire signal and other ground http://www.stewartwarner.com/wp-content/uploads/2018/12/434956-Traditional-Electric-Gauge.pdf David

I didn't see any adjustments to set the fuel gauge. I guess you could start with an empty tank and add fuel 5 gals. (20 gal tank) at a time to check it's accuracy.
