It's most likely a FASTRAK pump arrangement on that one. Those pumps are a bit pricey unfortunately. Average price is around $200 for one(aftermarket or OEM), and I doubt you'll get a penny more for it so long as the one you have now is working. Post up a pic of it to make sure which one you have.
This one is about the cheapest you will find.

I have a brand new one in the shop that was a $200 ARCO I could sell for $150 if you wanted.
