Fuel Petcock Diaphragm for GY6 50cc 125cc 150cc Moped Scooter
[330-999001]

Thanks. When I got the fuel diaphragm I looked at it and the nut looked to small in comparison to the original one. Inner dimensions right on target. Perfect fit and I am back to riding. By the way my scooter is a 150cc.
Service was fine. Still need a few parts - ordering soon.
