I have a Q2000 Model # G0068660 generac generator. The part that senses the fuel level is bad. I called generac to order the part and they said it is obsolete and gave me two other outlets to get the part. I called both of them and they do not have it. I then called two other places and they do not have it. The generator is under warranty. Generac part# is 0k6619. Anyone else run into this and does anyone know where I can get this part?
