My wife and I bought a 94 Palomino Colt PUP about a month ago. We have been on two trips so far. Loved it just got back from a week long trip in the NC mountains. We live right outside of Raleigh NC. We are having an issue with our water system. We can't get the water to the pump faucet from the internal water tank. In a bit of a pickle now because I also can't get the water tank to drain and the tank is full. I found the drain but nothing happens when I turn the drain in the PUP. The pump faucet is only pumping air out of it but no water. Any suggestions will be much appreciated. Will post pictures of everything.
