Help! My steering quit! (PROBLEM SOLVED)

I asked why just in case there were other symptoms.

Man, I hate doing preventative maintenance and then having something else go bonkers..

If it initially worked after the hose swap and then stopped, I would definitely do like suggested above and remove both lines to ensure they're clear. When hoses degrade they can shed bits and pieces into the fluid stream and block or clog stuff.

Might be worth removing the flow valve to make sure it doesn't have something in it causing a low pressure problem.
