If anyone needs a pump I have 2 brand new ones that I would like to get rid of. One I ordered specifically for this purpose and should be able to absorb anything a stock class motor can put out, it was fairly inexpensive. The other one is much larger and could "probably" absorb anyting a 4 cycle kart motor can put out. It is an expensive, high quality pump. I will sell either or both. if any one is interested post or PM me and I will dig up the brand, model and specs. I will sell cheap to get them out of my shop.
