Hello- We recently purchased a 2014 quicksilver 10 and have been unsuccessful in using the tank water system. City water works fine, but when i hook up the tank water hose to the faucet i can never successfully draw water.... it just keeps pumping air? We bought a Rocket pump faucet thinking we could replace the current set up, however it is a single hose system where as the current stock faucet is a two hose. Any advise would be greatly appreciated.
