Fuel sending unit

When I refuel it takes several minutes or miles for fuel gauge to read full or miles left before needing more fuel. last time 10 miles to register, is this normal? I am replacing the charcoal /carbon canister. Will this do it?

Re: Fuel sending unit

Welcome to the forum Gary. The gauge is sometimes a little slow to register but there is also the possibility you have or a PO has caused some damage to the sending unit tube. This can be done by putting the fuel filler in pointing towards the back of the bike and it impacts the sending unit causing some damage.

Here is a video by Kirk Johnson showing the damage and the repair process. If it still moves to full, then there may be some slight damage requiring some vibration to get the float to move past the dent. Worth a look.

Re: Fuel sending unit

Is this new behavior or has it always done this. If it does eventually read full there is probably nothing wrong with the sensor. It is not an instant read and there is some delay otherwise your fuel gauge would go up and down in every corner you took.

Re: Fuel sending unit

I see this if I don't turn off the key when I get gas.
