plastic vaccum stops in vacuum lines

[Boosted]

Hey everyone. New Typhoon owner here! Stock with the following Mods:

Already had the pleasure of the fuel pump fiasco. Factory lines and sender were trashed Ended up running external pump, sumped tank, and braided line with AN fittings.
K&N filter in stock airbox
3 in Flowmaster dumping at axle


Here is my question:
The plastic vacuum stops. Does anyone have a pic or can post a pic of the placement of them in the vacuum lines. I have already run the 3/4 heater hose and managed to mess up the vacuum lines. I found a diagram and ran all new vacuum lines and the truck is behaving and running, but I cannot remember where the "vacuum stops" belong. Any insight?

Thanks for the help. I am looking forward to many wrench sessions and already loving the Stigma that goes with these trucks.

If you mean the check valves, here is a diagram of them all.

Seems like even looking under the hood can lead to vacuum problems.
Hopefully you have jerked all the stock vac lines and replaced them by now.
Those rubber elbows and metal crimps are prone to leaking now that they are 10+ years old.

Best of luck getting it breathing back to normal.

oh hell yeah. Perfect. I will be making sure all is well in this department.
I thought mine only had 2. If'n I managed to loose one, any idea where I would get replacements?
