My pump probably needs replacing part number C23033, its making a terrible noise, I have not stripped it yet but I can imagine worn bushes and rotor gouging the pump ring or worse, I have not seen these parts for sale only refurb pumps with silly core charges.
The pump sits inside the reservoir type. It is apparently the same pump as fitted to many American vehicles 1963-1975 does anyone have a GM or AC Delco part number for the same pump? It’s a 5/8ths shaft with key.
Also do you know if this is simply a straight fit (reservoir and pump) or do I have to remove the new pump from the new reservoir and fit the pump into my old reservoir so that the mounting studs etc are all correct?..and it is period correct I guess.
Any help and ideas appreciated
