2001 Seadoo GTS Fuel Issues

[arimattes]

I have a 2001 Seadoo GTS (the older hull 5551 one) and it died on the water for me the other day. I just replaced all the fuel lines because they where still the old grey ones but there is still no fuel getting to the carburetor. I soaked the fuel selector knob in some isopropyl alchohol and it looked clean but that seems like the only possible thing it could be. Just looking for some help, thanks.
