The pump on that unit runs off the timing gears at the front of the engine. Its that aluminum colored piece that the two steel lines come out of. The large block of cast iron below the fuel tank is your reservoir and the actuator for the cultivator lift arms that stick out of either side. I can't tell from the picture, but you should have a control lever up by the steering column that will control the system. I'd make sure its full of hydraulic oil (should be a dipstick or fill-to plug) and then fire the tractor up and try the lever. Beyond that I can't help you because my Farmall H has a totally different system than your Super C.
