Hi All, I’m working on a 1973 4HP yacht twin. The fuel pump has number changes as follows: 0381815 to 0386833 to 0388684 to the tune of $167.57. When did they start making them out of gold? Anyhow, I would like to rebuild it but they don’t list a kit for it. Does anyone know if one of the other kits may work for this one? Don’t want to take a road trip to China if I don’t have to. Thanks , Matt.
