Harley-Davidson gas tanks have few components that a rider can repair. However, you might want to remove one if you need to fix scratches or dents or you want to have a custom paint job done. Removing a softail tank is fairly straightforward, but you should do it with a safety-first attitude. The battery should be disconnected and the fuel drained before beginning. This also means removing the seat before starting.
