your looking for a -6AN to metric female flare fitting (i've been loking through the Aeroquip catalog for this and i dont have a clue what would fit without trial and error)
if you have an Aeroquip dealer or Air/Hydraulics supply place that will build lines, you could take it to them and have them find the proper adapter for ya.
(hmmm when it gets warmer i might go to the junkyard and rip a pump out and see if i can get a difinitive part number for this)

the one on the pump is an Inverted flare and IS NOT a 37* SAE flare

most people end up hacking off the fitting abd brazing on a -6AN fitting. i would recomend that!
just remember that you need to add in a fuel filter after the pump and before the rail. i use Aeromotive ones with the replacable filter but there are cheaper ones out there, just make sure its for Fuel Injected engines and it should be a 10 micron filter.
