Bosch 070.  Bursons seem to keep them in stock (bought 2 in recent times!), around $150-160?  For some reason cheaper than the Bosch pump for a VL commodore, which is the same thing with a slightly different number.  For the price, I wouldn't bother screwing around with cheaper variants, stick a genuine Bosch in and it'll probably last another 20 years.

hi there the ones on ebay work fine i got one for my alfa 90 and have had no troubles since plus they r the cheapest around
