Hi i have an 04 Gilera DNA 50, when im riding on my bike the fuel level keeps flickering from low fuel and light comes on and then says full tank and keeps flickering between the two, it stays on empty tank for like 2mins then will pop onto full tank for 5 secs, then back to empty, i've been told it could be the fuel level sender but i dont know where these parts are located, Please can someone tell me is this correct that its the fuel sender or a display problem as it is a full tank full to the brim and where the parts are located if i need to replace them.
Thanks for everyones help.

Hi Ian,
answer I found from Steo. Top bloke from 2009

Your fuel sender unit (measures the amount of fuel in your tank) is banjoed or the wires going to it are disconnected. Have a look at the top of the petrol tank for two wires which connect to the fuel sender, they're obvious enough probably black & green wires. Are they connected?

If they're ok then have a look at the sender unit. It should just screw into the tank & easy enough to take out. It works a bit like the float in the cistern of a toilet in so far as the more fuel you put into the tank the higher the float rises. Check if this moves freely up & down. Connect the wires to the sender unit & switch on the ignition. You should see the fuel gauge moving if you raise the float arm, if you don't then the unit probably needs replacing.
