Fuel gauges

If a tank is wide and voluminous, i.e. it will contain a full 5 gls, and if it is also one-piece and actually only needs one gas cap, then one could ... exactly: where you would expect the left-hand gas cap on the Road King and, from 2000, on the Softails, there is a fuel gauge. And while some are still pondering the sense or nonsense of this part, others have already developed a custom replacement with an LED display for the original pointer instrument. Because one thing is clear: if you replace the gas cap on these models, you'll also need a matching fuel gauge to complete the look.
