I have a leak in my power steering right where the pressure hose from the pump connects into the rack and pinion. My problem is I have tried different things to stop the leak. I tightened down the connection there, and fluid still comes up out of it. I tried to put an o-ring there, also tried that teflon tape. Everytime i tightened it down, but I can watch it slowly leak. Enough that I have to put in more fluid the next day. Any suggestions to fix it? Am I missing something that prevents the fluid from flowing back up out? Thanks in advance.
