48 pump

[poorbiker]

Figured it out. Sometimes the more I read the more I dont know and I dont know alot . It might be a 48 pump doesnt matter its just he same as the 41-47. I do have a later complete pump that doesnt have the centrifgul rotor or the machined pocket for the rotor and the correct plate. But still cast iron cover, Im guessing its a 49-to early 50, thinking about using it on my knuckle build.
Sometimes your thrown for a loop when you buy a complete pump from swap meet or vendor or anyone and it comes complete but with wrong parts, it all fits but not for the same years, love that........
