I fixed my Rhino's gas gauge.
I know a lot of your rhinos have the same problem that mine had; the gas gauge wasn't accurate. With a full tank, after just a few minutes of riding it would indicate 3/4 of a tank. And with more than 1/2 of a tank it would indicate empty and begin flashing.
Here's what I did.
1. Remove the fuel pump from the tank.
2. Remove the float lever from the pump.
3. Remove the fuel gauge sending unit from the pump.
4. I bent the 2 little contacts that move up and down the sending unit in such a manner that they make better contact with the sending unit.
5. I also wiped down the resistor with just a few gentle strokes of a lint free cloth.
I didn't bend the contacts very much at all, maybe 1/8" or so.
My gas tank was nearly empty. There was only 1" of gas in it. I went to the gas station and bought exactly 4 gallons of gas. I poured that in the Rhino and as I was pouring I could see the gauge increase from the flashing "gas pump" symbol indicating EMPTY (mine had never done this before, btw), to then the flashing first segment with the "E" indicating 1/4 tank, to the second segment indicating 1/2 tank.
I'm pretty happy with it, and it didn't cost a thing. The entire job took about 15 minutes. And the hardest part was getting the fuel line to disconnect from the fuel pump. I just had a hard time sqeezing it to get it to release.
I hated not having a properly working fuel gauge. And I didn't want to add an aftermarket one because:
1. The Rhino has a gauge, and damn it, it should work properly.
2. And because I think having two gauges in the dash is like putting the good tv on top of the bad tv.
Good luck to anyone who tries it. It's a piece of cake.
