I have been looking at my 87 GLHS vacuum solenoids and comparing them to other pictures in here. I have also seen where you can purchase foam filters to add to these solenoids.
So here is my question, when I bought my car last month, in the picture is how the solenoids were configured. I just noticed that all unused solenoid ports have caps on them and I thought why have foam filters if they are capped? Are these unused ports supposed to be uncapped and would this possibly cause my car to only see 7lbs of boost?
The previous owner also had a boost gauge hooked up to a vacuum line off the intake manifold and I cannot tell where it was supposed to go (with gauge removed). I have verified all the vacuum lines are correctly routed off the solenoids and intake, so it leads me to believe it is an unused vacuum line coming off the back of the intake. Hopefully someone can tell me if there is an unused vacuum line and I dont get to play find the missing vacuum connection.
Thank you in advance,
