Curious whether I can route my FPR vacuum hose to a nipple on my plenum(same size) instead of that stupid throttle body block thing(would love to just plug that, not using the other port on it) just not sure if it will see the correct amount of vacuum there. Also would rather not plug the nipple, for some reason the nipple vacuum caps always seem to fall apart in a couple months...

 

Yes, plenum vacuum is fine.

 

K, thx for the answer, I figured it should.
