Bolt thread size steering rack?

Hi, I'm currently doing my powersteering line on my RHD S5 Turbo 2. I've put some -6AN adapter fitting on the rack itself but I still have to plug the "balanced" hole on the rack. I've try M12x1.25 plug it only goes for about 1-2 thread than stop, I don't want to forced it. Am I using the right plug or not?

Thank

Good to know! Thank you! Also do you know the thread pitch for the feed and return? Also why are you plugging the balance?

M16x1.5 for both return and high pressure ports on the RHD racks. LHD rack uses a M12x1.25 for the high pressure and M16x1.5 for the return line port.
