Help with older hks Super blow off valve

[andrave]

Can someone tell me:
1)
Why do I have two vaccuum fittings? which one is which? I'm a little confused, especially since they are used and the vaccuum lines that came on them had them both teed together. Why do I need two fittings?

2)
how do you remove the vaccuum side, where the diaphragm is? is it pressed on?

I searched and emailed HKS but haven't found the answers yet.

thanks in advance.

I'm going to be running blow through mafs so I guess it doesn't make a difference, leaking at idle is fine with me, I suppose I'll go for the boost/vaccuum duo and if I have problems just tee them together.

thanks for the link, anyway.

nice, mine will be like that, times 2.
how do you like the sound?

its perfect, not too loud, but still audible. and its release is quick without any whistle effects.:)
