If not, your engine will likely get a big gulp of your red fluid.

My suggestion (as I considered doing this myself) is to get two dial vacuum gauges from Harbor Freight or somewhere similar. They are accurate enough and just require a homemade dampener (or pinch the vacuum lines, but that's just a pain in the butt).
Here are the gauges - www.harborfreight.com/fuel-pump-and-vacuum-tester-93547.html - less than $30 for a pair.

Now it is hard to see if at the bottom of your set up, are those T'd together? You have 4 lines, how are you going to use 4 at the same time? 2 should be together pulling the fluid at each end of 1 hose. Or do you have some restrictor in the lines somewhere?

but I've tried the dial guages, and they are a serious PITA.
Not to mention were trying to get the vacuum matched across all cylinders within 2 cmHg. That is just impossible to do with dial guages.
They're not even that accurate from the factory!
A homemade manometer works very good with some homemade restrictors.
Or a Morgan Crabtune, which is the superior unit to all I've tried so far.
Whatever way you go, accurate balance is key to an optimally tuned engine.

This depends on the quality of the guages. I have one set of 4 that I believe use astrology to predict the vacuum :laugh: But I have another set of 4 high quality guages that an engineering friend gave me that work really well. I'm sure the Carbtune also works well and probably would have bought one replace the cheapo guages if I hadn't been given a quality set. Ed

I said Morgan Crabtune... :laugh: Whats this Carbtune thing you speak of... :laugh: :laugh: :laugh:
You're right though, I have seen some nice EXPENSIVE guage sets... the cheapo ones just don't cut it.
I actually caught a factory race team using the Morgan II Unit
