    My Kubota SVL75 track loader has been sitting unused indoors for a 10 months in an unheated building. It started up just fine today, but gave an error code E:9120. I turned off the engine, removed and inspected the fuel filter, visually everything is fine with the filter, but error E9120 still appears.
