Wont the hose have to be longer on one side or the other to create enough pressure to keep the flow uphill?
No.
As long as the output end of the hose/pipe is lower(closer to sea level) than the input end, the position of the high point in the hose is irrelevant, except that the greater the length of section A, the stronger the pump you will need to counter the additional resistance generated by length. This is in addition the resistance generated by height. This total resistance is referred to as "head". Turns in the direction of the hose/piping also generate additional head. A pump with sufficient head pressure will be needed to overcome this. Once the hose is filled to the point where water begins to flow over the high point, gravity will take over. Flow rate will be determined by hose diameter. As long as no air is introduced on the input end the water will flow using only gravity until the supply runs out.
