Below are a few videos that may help you as well as an instruction sheet.
It's important to keep that plastic neck o-ring super tight and only open the pump handle by twisting the pump handle. Then fill up the water with the entire pump shaft removed from the tank.
Both valves (shower straw and release valve) on top of the tank must have a small rubber o-ring inserted inside, this keeps the air sealed. If your valves do not have rubber o-rings please use the ones provided in the small plastic baggy. It is also ok to double-up on the o-ring's for an extra seal.
