First these manuals are very vague with specific information.
OK do this in segments. Got water is in the tank. Water from the tank is getting to the pump. Water is getting from the pump to your faucet. The pump is 12volt, there is a switch usually near the faucet, needs to be on. Is the pump working, break the line between the pump and faucet to see if water is being pumped. Also the pump has a mesh strainer and that needs to be clean. If water is being pumped through open up the faucet and you should have water. If not you might have a water line disconnected, check that.
So follow these steps and you will have water!
