Review on KELCH 7J203658 Gauged Golf Yamaha by Jay Ngo

As a gas cap, this is an excellent product. However, this gas cap was ordered together with the fuel pump and the new carburettor. Spent weeks fixing fuel pump issues thinking it was a new carburetor. They brought in another fuel pump and then found that the gas cap was causing all the problems. After 4-5 days, the fuel pump will fail to pump fuel from a tank with a non-vented gas cap. Lesson learned, so make sure you poke a small hole in that gas cap.
