I cant seem to get the power steering pump hoses off of the flared tubes coming out of the pump. Truck has 90K on it, so they might be a little stuck, but is there a trick to getting those hoses off of the pump? yeah, I moved the clips back. These are the LP hoses. The HP hose at the bottom of the pump is on a thread fitting.

Thanks

Are the lines rusted so the collar wont turn? You can get a high pressure hose from most auto parts stores for under 50$ I think.
The return line is just a rubber hose over a barbed fitting, not sure if you mean this one. If it is, just slice it off and get a new hose.
