Kitchen Faucet Repair

So last night I was rinsing off some oatmeal from some bowls before putting them in the dishwasher. Our faucet is one of those that has the sprayer integrated into the spout, and you can pull it down and out of the arm to spray with. I pull, it is stuck, I look under the sink, slide it forward off of a pipe, and pull it down. When I'm almost done I push it back up into the arm, and the water quits coming out of it and I hear spray under the sink.

It is a one-hole unit where hot and cold lines hook in, and then go through a connection that has the hose going up and into the arm. That hose got pinched on something and has a split in it. I need to repair or replace it, but my searches at home depot and lowes websites is coming up short. I'm trying to avoid buying a new faucet at this point.

It looks very similar to this Price Pfister model.



Any ideas?
