For the fuel gauge. You have to replace the entire fuel pump/gauge module.
Just went thru this.
The gauge is a Singapore cheep thing.
If you're a good handcraft, you can try to pry back the tiny pins
on the gauge but good luck.
Can find the module on E-BAY.
Take care not breaking the fuel lines when you drop the tank,they are very short and they pass over the top
tank straps.Hard to disconnect too.
