Compression tube for front mount install

Ive been searching this for a while and just cant seem to find the right answer.

Im installing a front mount on the FC and am having trouble getting the compression tube installed. What I cant figure out is how has everyone installed the tube with the vacuum valve and metal piece that holds it in the way. No one seems to talk about it. I cant be the only one that had this problem. Im sure if I cut the bracket that holds it maybe I can do it but there must be an easier way. Maybe my compression tube doesnt have the right curve but I looked at the greddy and its identical.

Thanks

Guess I'm stumped as to which piece you're talking about. Pics? I'm running the Rx7store FMIC kit. No install issue. Just a little tight near the brake master cylinder.

The marked valve is the problem. It also has a bracket that holds it. It is completely in the way.

Just unbolt it, lengthen the hoses and move it out of the way.
Assuming you want to keep it, that is.

Why guess?
Look at the FSM, figure out what it is and then decide.

I'll help him out clokker, It's the purge control valve. It relieves crank case pressure. You can't just get rid of it and be done, you still need some sort of PCV system.

As others have said, in most cases by the time we get the cars the parts are gone. Hell, mine doesnt even have the hard metal tubes in your photo anymore nor anything that looks like a pcv system. Just vacuum hoses to a bottle. (which i need to work on even though the motor appears to vent nothing at all.)
