Default Thread size of wastegate and bov vacuum lines

Well I'm looking to find out the thread size of the wastegate and BOV vacuum lines. I'm going to buy some vibrant push lock pneumatic fittings and I don't know the thread size that goes into them. Thanks!

Tial 44 mm and Tial q 50 mm....I will also need the size of the thread pitch of the MAC boost solenoid, those 2 will need fittings. And the size of the line.

I just PM'd you on this lol. You have to retap the threads to 1/8 NPT

The metric threads are close but its easy to just run a tap through them.

Yup. I did the same when i had clearance issues with my tial 38mm. The actual thread is metric (10mm i think), but an 1/8 NPT is very close. Just retap and use a little gasket sealant for assurance. It has held fine for months now
