slip on outlet . and give it a suck .
.pull off hose . i bought a piece of clear hose from home depot . not cheap . 5 - 10 $ 4 a couple feet . hobie tank comes with a black nipple connector that scoops up the water to prime the tank . this nipple attaches to the inlet hose which runs through scupper . a few strokes with paddle or peddles forces water up into the inlet tube via scupper hole and you are in business . having tank primed or filled doesn't hurt either . all these parts can be purchased separately . but take a look at hobie catalog and you can see all the hobie tank parts and get an idea .
