fuel pump, What is an early to late fuel pump conversion Options

[hndyhrr]

Hi, purchased a fuel pump from 914 Rubber. Their part number is 043 906 043 The pumpkin is a 70 4cyc. Web site says I need an early to late fuel pump conversion. Can't find anything on website for that.
Anybody have a Idea what I need . I have sent 914 Rubber a msg via their contact us email and waiting to hear back but really don't want to wait in case some one knows about this.

Thanks

an additional tip.

modern fuel pumps are not made of rigorous germanic materials on the interior operating bits. my view is if they shite themselves at some point its down the fuel lines to the injector. i would install a high pressure fuel filter after the pump. the line up from the pump into the engine bay near the battery is as good as spot as anywhere.

this will save your injectors from ingesting whatever a blowing up modern pump wants to let go of.

VW never bothered with a filter after the pump a half a century ago. the old three port pumps could operate at ground zero at hiroshima and still keep going and if they did decide to die as a result they really did not send any material down the fuel lines to the injector, but thats just a precaution you can ignore if you are not worried about injectors.
