Wonder if they would have what I need?

I just noticed that there is noise coming form the engine compartment of our van when ever I turn the steering wheel.  I bet there is something wrong with the steering hose.

Wonder if I could find what I need at Delafield hydraulic hose on line?

In the past year, I have been just adding power steering fluid which has fixed the noise problem.  With out really looking however there must be a leak some where causing the level to go down and thus the noise.

Then again, maybe I should take the van to someone who knows about such things and let them tell me what is needed, and not do it myself.
