    Hi all
    I recently purchased a 2009 FLHTCU (Ultra Classic) and the fuel light comes on when I fill it up, but doesn’t come on when I get low on fuel. My first guess is something is connected back to front. Before I pull the tank apart does anyone have any idea where to look first?

    If i recall there's a electrical connection under the tank but it only plugs in one way. Check the fuel sender inside the tank would be my first look.

    Some fucker may of done some dodgy shit in the past, I'd start with wiring on the outside, then the sender unit itself.
