Just browsing for info on the net and found this http://www.jegs.com/i/Melling/689/10227/10002/-1
Noticed a few people buying these for a tad over $300 for the whole pump and billet gears and fitting them to ba XR8's. I was quoted $540 for the gears alone (BPT Units) Seems like replacement gears are extremely overpriced compared to this unit. Even Ebay has them for $300 US http://cgi.ebay.com/ebaymotors/Melling- ... 0354403963 Need to find a supplier in Aus for sure

I used a stock 3V/GT500 pump in mine but this is the best one to use...
