If the kink is above the floor, you'll get a little dribble in whatever back-flows from the hose to the pump, but everything downstream of the pump should stay there and any water on the tank side should drain back to tank.
That depends on whether the tank is also above the floor or not. If the water level in the tank is above the work site, you create a siphon and get a tankful of water on the floor. If it's below the work site, the water stays in the tank. On my RV, the tank is above the floor (under the bed) and next to the pump, so I would want to drain the tank if I had to do work such as is described.
