I posted this on another forum so I apologize if you've already read this. I bought a scooter and the fuel gauge isn't working. I had to transport it home in a ford explorer so it was lying on its side for the trip home. It was full of gas too but I don't know if the problem already existed or not. Does anyone know how to fix this?

First you need to know if it's the gauge or the sender in the tank. You should be able to probe 2 wires with a multimeter set for resistance and get a reading that will vary depending on the amount of fuel in the tank (move the scooters to slosh the fuel around and the reading should fluctuate). I'm not sure what colors the wires will be, depends on the scoot, but there are usually only 3 wires from the sending unit so it doesn't take long to figure out. If you are getting a signal coming out of the in tank sending unit, move up to the connection to the fuel gauge. See if you get the same signal there. If not, check your wiring. If you are getting a good reading there you have a problem with the gauge itself. Replacement of the gauge or gauge cluster should be very straight forward, as is replacement of the sender. If it's the wiring you might have some time into finding and fixing that.

Turned out to be a pretty simple fix. I just let it get down to a little less than half a gallon of gas and shook the back end of the scooter. I then filled it up and I could actually see the float coming up with the gas. Switched it on and it worked. It must have just got stuck because of the way I had to transport it.

Good, i love it when stuff is free to fix ;D. Now i will feel silly if mine is stuck from a wheelie or something. Its not been working for a few weeks  , i just take the g-cap off and look when i suspect its low. I think i might get a new tank this winter and maybe a new sending unit because i didnt realize how dirty this tank was until i started going through fuel filters(3or4 so far), that probably why my sending unit quit working. I would assume the guy i bought it from let it sit for a while low on fuel and it attracted moister and got rusty dirty  . At least these filters are doing their job though. I would rather replace a $4 filter once a month than rebuild a motor because it tried to burn dirt  . |

If you have a trip odometer that's a lot easier to use than peeking in the tank. I run no fuel gauge on my stripped Triton. I know I get 40MPG and I know I have a 1.4 gallon tank, so once I hit 40 miles I try to get gas to be on the safe side. I like this method better than a fuel gauge. I have a better idea of the amount of gas I have this way. The stock gauge is much like most cars and trucks where you get half of your distance by the time you get below the F mark so it's not very linear. If I see I've got 20 miles on a tank I can pretty much gaurantee I need a half gallon of gas.

I dont have a trip odometer, good idea though, always know yer current mileage that way.
