Right guys & girls,

I have just purchased a AS inlet manifold & it comes with a o ring groove where it mates to the tuumpet/injector section.
All ok


But...

I have just gotten hold of another trumpet/injector section that has been machined for o-rings where it mates to the head (nice I thought) but... It also has the face machined for an o ring where it joins to the AS inlet

So to put it simply:

My inlet & trumpet section both have an o-ring groove where the mate together.
Is this doable or can this not be used?

Where can I buy new o/ring kit?

Cheers
