Vacuum sources created equal?

[94v6GT]

i have a couple of things that run off vacuum, (gauges,BOV etc.) so im getting creating with the sourcing. Are all the vacuum ports equal? will i get the same signal from the vacuum tree as i will from the Intake manifold port? Also if i tee into the FPR vac line for an FMU, will that effect performace of the FPR

Im guessing its all the same but i wanted to run it by a few folks.

I think as long as you don't create to much volume of vacuum you should be ok with tee-ing things off. I redid the whole vacuum system in my car using a 1.5"x6" long piece of pipe as the new tee. It sorta created a vacuum lag everywhere and overall less vacuum, bad. So going back to something as small as the stock tee and tapping more lines directly to the upper plenum took care of that. Vacuum systems are strange. I would suggest that running as much as you can directly off the plenum would probably be best, but tee-ing off once per line won't hurt anything.
