My question is about the fuel pump and what was the OEM pump that was installed on the original 1966 U13. I was told the engine was original and it has a fuel pump that has a glass bulb on the bottom. I am being told that the OEM fuel pump did not have a glass bulb, but I see where different sources are selling the pump with the bulb. Does anyone know what was installed on the early U13? Mine was manufactured in mid-September 1965.
