Installing the pressure and return lines to a new PS rack, I find the
pipes inside the fittings are loose - not can-position loose but
gonna-leak loose. I've seen some posts that say I need to get new
hoses with new fittings to cure this and some that say replacing the
rubber 'O' rings at the end of the inner metal tube will fix this.
Which is it? I have replaced the outer nylon 'O' rings via the proper
method and they are fine.

Sorry for no replies but your description of "gonna leak" is really
subjective.

I've replaced those lines on an earlier model rack with the same system
of nylon o-rings, with the same feeling of 'dread'.. but they did not
leak.

Thanks! It's been tough finding anyone with experience on these.
Perhaps the pressure helps seal them. 'I'm pretty certain they are
going to leak'- loose, floppy loose. Not the firmer type of loose that
allows one to position the line but will hold pressure. I'll post back
to this thread/topic when I get it solved or find there was no problem.

The last PS rack I changed on a Ford (Fiesta in fact) felt exactly like
you describe. It was the same before though and it didn't leak before or
after.
