I will call Sean - The Monark pump is basically just an original housing shell with all NEW internal parts. The alda, elec idle controler, elements,and everything is new. It was shipped from Germany to us. Apparently, they are the supplier for MB now; but don't hold me to it.
Again, only about 300 miles on it so far.
Here area few pics of this expensive part....(Sean came over to help me install it)
