I have a 2008 trailblazer, pressure line on the back of the rack is leaking. I pulled the line out and replaced the O-ring that was bad with a 3/8 Ring and it’s smashing the new o ring causing it to continue to leak....and I missing something?

Thanks for any help in advance.

Are the power steering lines the factory originals? If so, it appears that the factory ones used a cup seal and not an O-ring in order to seal the lines to the power steering rack.

If that is the case then you will need to use either the ACDelco cup seals P/N 26080380, or Gates P/N 349572.
