KuHL 951

Does anyone have the size of the wastegate tubing off the WG hard pipe? I need to buy the vac tubing for this connection at the hard pipe off the wastegate. SAE or metric is fine, does anyone have the answer quick? I'm in the middle of a venturi delete/MBC install and found the tubing completely gone. Gee, that explains a few things with why it built 'good' boost and I would have to back off so soon at 15psi
TIA,
Steve
