Just a few thoughts..

If there was no reproduction parts, complete pumps would be far and few between... and just think where the prices would be at.. most of us could never afford a complete pump if that where the case..

Now I appreciate the fact that you can by aftermarket parts for pumps, but it also holds down the price on originals.. which can be good or bad..depends which end of the deal you are on...

Now I am thinking of a problem that will show up, and I am not slamming the dealers when I say this. How many times are pumps sold to buyers as real and all complete when they may have 1/2 dozen or more repo parts on them?? They parts as far as I know are never marked and it largely gets ignored...
