This brings up an interesting issue...is the 10p15 better than the Sanden 507? I did a quick search and had no trouble finding the Nippondensos for the 80s Carreras for sale at decent prices (rebuilt obviously). It looks like they have a different hose connection set up...is that hard to deal with?

From what I have read the Sanden does not compress as much volume so it is less pumping action. It does need a diferent bracket and hose connections as I recall. Ask Griffirth's. He can give you the facts.
