    I got a Fisher minute mount on a f350 with a electric pump and controller, every thing works but when I rise it, it just falls right back down. How do I fix this, what do I need?

    The internal check valve in the S1 valve is stuck open or the valve itself is stuck open. You can try removing it and cleaning it but usually they need to be replaced. The valves are located on the rear of the pump unit under a plastic cover. Here's a pic with the S1 valve location:
