What I did - 1/2" PEX barbed nipple on my coolant reservoir hose, and 3/4" of the same for power steering, where the accessory pully kissed both. Car ran fine for a 14 mile test drive, without leaking anything. It was nice being able to shift quicker without the engine lurching now that the dogbone mount is done properly with that Timesert, and I'm very happy with my latest Podtronics tune. Even better, that requested and actual boost are damn near spot on. I'm still very disappointed from the logs I got when I still was running a Malone Stage 4 (but on my 2002 Golf - the 2000 Golf came with a mystery tune on the ECU, that we think might be Kerma), where there was a big disparity between requested and actual boost.
So when I get back from vacation, the 2000 Golf is getting Neuspeed sofsport springs, B6 dampers, neuspeed 28mm rear swaybar, replacment AC compressor (so I can do my AC job right the first time), new radiator, and associated radiator hoses and flanges, so $hit doesn't break while I'm driving (ask me how I know).
