That is a really cool replica, Ed!  And I know how hard it is to get those internal rubber parts reproduced.  I tried and abandoned that direction when confronted with up-front and reproduction costs for my heater fuel regulator.  $60 - $80 per diaphragm was out of sight for me, but not to those deep pockets out there seeking authenticity.

There is a shop in New Jersey reproducing those pumps to original drawings, but they are STILL unobtanium, as the Spyder Factory has them under an exclusive contract.  I'm not sure who's doing the cast parts (the NJ guys aren't) and suspect those come from a foundry in NH or Mass. - there are several foundries doing cast aluminum and other metal parts around here.  All of the work involved in making faithful parts to original drawings is probably why the reproduction 550s are now over a $Mil each...
