Review on WonVon 2 Inch 52mm Universal Car Motorcycle Fuel Level Gauge, LED Fuel Tank Gauge Display with 12V Light for Boat, Truck, RV by Robert Grind

Comes with a tiny potentiometer for full scale adjustment, which was important. Replaced the counter which was held in place by a threaded ring so I had to use silicone sealant to hold it in place. The display is VERY bright, but the response is VERY slow. It doesn't matter if you only have one tank, but I have a two-foot (and only one-foot) toy tractor on wheels, so I had to hold down the tank select switch for a minute to see what the actual level was. I replaced the switch with a fixed (not momentary), now everything is fine.
