Power Steering Hoses

My PS high pressure hose sprung a leak.
I haven't taken off the hose to replace it yet. Just located the leak.
Is the hose seperate of the pump?
Can I buy a hose and just replace that or do I have to buy both hoses and pump all at once?
Looking at it from the top it appears that its a solid connection to the pump.

Thanks!

With the limited info you gave, I can only guess what you are driving. The power steering hose will have a nut on both ends if it is the pressure line. You should be able to get one at your local part store or dealer.

Sorry...

Can you get to the nut on the pump without having to take the pump off?

Thanks
