You can buy a pump now which will support your carb, for cheap, and buy 
a pump and regulator later to feed your EFI.  This route would likely be 
less complicated / expensive and just as effective as buying one pump 
and either (1) buying a trick regulator or (2) rigging two regulators or 
some other setup to dump the massive excess flow you'd have running a 
carb with a pump designed for EFI.
