Just bought a L2501 2 days ago. Have 3 hrs on it, fuel tank is less than half full but the fuel gage indicates full. Can't believe it. Found sending unit wire on top of fuel tank, Disconnected it and the fuel gauge goes to 0, So that means the resistance reference is getting to the display but it's not displaying correctly. Is this fuel system a float system. Any help is appreciated otherwise I have to bring it back to the dealer
