I have what I believe to be factory 1983 steel fuel tanks in mint shape. But they have gauges in them similiar to the Rochester gauge
but the name on the gauge is Mirax Products St Louis, Mo
Dial #5-00837. The gauge works but I would like to change out as the boat is completely restored. I tried to find some info on the Mirax Company but no luck as yet. Do you know if these gauges were factory pieces?
