When I did it, I think I had to pull the elbow off. If you look closely, there's a short piece of tubing or something that connects the hose to the pump itself. you should be able to reach one of the two bolts there in order to disconnect the hose from the pump. then just pull it off with the little elbow intact and install it on the new hose while you have it out of the car.
It's been about 4 years since I had to do that so I'm a little fuzzy on the details. good luck.
