I have a 05 720 gti (single carb), i believe the oil tank is leaking (getting 2 stroke oil in bottom of ski). I am going to remove the pump and use a block off plate. Does anyone have instructions on this ski on how to remove pump? Can i take the tank out if i remove the pump? Where is the best place to buy the block off kit? I know a lot of people believe in these pumps, but i have seen multiple power heads on boat motors blow due to the pump, removed the pump started premixing, never blew another power head.
