fuel gauge not workin

hello
fuel gauge in my 68 beetle not workin
would it be a faulty sender unit in the tank or can anyone help
thanks simon

Easy way to check the sender in the tank. Put the ignition on and temp connect the two wires at the sender if the guage moves then it looks like the sender if not it could be the guage. I’m assuming you have checked the fuses.

hello yes checked fuses
and i think from memory there’s only 1 wire on the sender ontop of the tank
thanks simon

If it only has 1 wire touch it to earth and see if the guage moves
