I am not sure about the 900's, but Polaris has always used a mikuni fuel pump. Should be able to buy a high volume pump anywhere. If not call Bruce at PSI... as much as I hate to recomend PSI (cause they are slow and expensive). He has fuel pumps for the big genesis engines, but then so do all the builders. You can also buy rebuild kits, they are a diaghphram that you replace in the pump. Royal Distributing (www.royaldistributing.com) has these kits, and probably the new pumps too. Guess I should have asked if it was injected, but there is enough info here to find a vac pump or electric.
