What a cluster fukk! Of course the Delphi holder assembly is made differently (the pump is smaller and the isolators are at an angle which is maybe better for noise) so only the Delphi pump fits into it and the Delphi pump, when ordered by itself, is to fit in the stock holder which is maybe why they put the Spectra pump in the box! So I don't how a person would get a replacement Delphi pump to fit in the Delphi holder, not that I would want another one, so yeah I withdraw my praise and replace it with criticism!
