I need to fit a vacuum hose to my throttle bodies, there appears to be threads tapped on the top and bottom of them, I’m after a rebuild manual that can confirm which I should be using (I’m assuming one set is bleed valve adjustment) or anyone have knowledge of which can be safely used?


Thanks
Alex

I never found a manual of any sort for them when I searched a few years ago

ATSpeed set mine up and other than a small compromise of a 1000rpm idle they still work great after several years. No drift at idle despite warnings from many that the idle would drift all over the place depending on the day of the week!

They may be able to help you or I did read that Northampton Motorsport are very knowledgeable on these so maybe they can help.
