really? well I orderd a pump here in Australia and it flows 3.5 gallons a minutue, and I found out the stock bosch pump flows 4 gallons per a minute. I canceled it but the guy got abit upset and is making me pay $50 for his troubles. Do you think 3.5 gallon pump will hurt my S/C? if not I may aswell buy it rather then giving him $50 for nothing.
