This one is easy. First, turn the ignition on (but don't start the
car). Second, disconnect the hot wire from the sending unit and touch
it to a good grou^H^H^H^Hearth. You may have to use a length of jumper
wire. If, after doing this, your fuel gauge jumps all the way up to
full, congratulations! It's the sending unit that's bad and not the
gauge.
Changing a sending unit is easy, but please do it in a well-ventilated
area. Nobody likes gasoline fumes exploding near them. Wait until the
tank is mostly empty, and jack the sending unit side of the car up.
Remove the road wheel, and gently tap the retaining ring anticlockwise.
The ring comes off, then the sending unit comes out. Have a new gasket
on hand.

Yup. Ask Thomas about the oil-in-a-baggie gravity feed thingie. A
well-lubricated cable is essential to smooth speedo operation.

As others have said recently, "There are no silly questions".
