Bill, you are correct that those are for manifold vacuum line. A= stock gasket won't cover them it has holes to allow the signal to pass int= o the manifold where they are combined into one.

It makes a very nice and easy connection for your MAP sensor. It= is in the perfect place (as close to the intake as possible) and combines = the 2 halves (as Tracy recommends you do)

I use it as my primary MAP sensor signal. I have another one at = the throttle body as the secondary. Both work fine in flight but= the primary seems to give a better idle.

Question: Has anyone used these -- or = did you just block them off with the manifold gasket. I speculate that they= are used to help give a puff of air on the injection cycle.
