Gear box thread size

[Hawaiian Turbo]

Anyone know the size of the gearbox threads? I'm looking into changing them to AN, but cant find the sizes. I believe the pressure side is 16mm but not sure on the return.

Thanks, Paul

One is 16mm x 1.5 and one is 18mm x 1.5. They are both o-ring fittings. If you look in the brake section I have a post on the hydroboost that lists fittings, etc.

THanks Tin Man, I'll have look.
