69 gmc air cleaner help......

[drsergio]

Ok
I can not put my original air cleaner brake with the new bigger power booster brake kit installed.

I got a 9 " round new air cleaner that fits perfct

was able to conect one of the hoses to the air cleaner
BUT,,,,,,the metal one that come off the manifold..( arrow on picture)
Do I need to keep that one hooked???

I already removed , but not sure If will make a difference on the running engine
some light???
