Xk8 replacement of gearbox oil cooling hoses

Hi everyone

I’m new on this website. I have a problem with the gearbox oil cooling hose on my xk8 4.0 2001, the one goes above the gearbox. I look for how to pull it out and then push in a new one, anyone can advise me? Hose reference is NJC4500AA.

Many thinks in advance

Kind regards
Jean Philippe
