MAP sensor vacuum question

Thanks.

I had thought about the PCV line but noticed that I've never seen anything 'T'd off that line in any application and figured it was for a reason like that.
And since I plan to have the HVAC controls vacuum line going to a vacuum canister, I figured that wouldn't be a good idea either.



This normally wouldn't be a problem but in this case, my intake manifold has zero vacuum ports. I had to add one for my PCV valve but forgot about all of the other things I would need while it was off the engine. So the only one I have left now is a small vacuum port off the base of my throttle body to use.

Thanks,

Here's another thing to consider. Keep the line as short as possible. or as close to the vacuum source as possible
