My Vacuum line going to my FPR has a T that is running through my firewall, Would this be running to a gauge or somewhere else?

Car currently does not run, im getting close but working on buttoning up a few things in the process.Probably running to an aftermarket boost gauge. If you have an aftermarket boost gauge easy test is to unplug that line and start the car. If the gauge doesn't read anymore that's it.
Could also be running to a map sensor on a speed density set-up and someone decided to locate the sensor inside the car. People do weird stuff with these cars
This is good news if it is running to my boost gauge, i wanted to relocate my FPR and the vacuum line was too tight. Id much rather pull it from the intake.Most likely to a boost gauge as that is a common point to tap for that.
As an FYI, some may recommend the tap should be moved and the FPR should have its own dedicated line, directly from the intake manifold.
Yes the clear tube is running through the firewallIs that clear tube also running through the firewall?
I guess the other question is where does the other end of your FPR hose (not running through the firewall) go to?
That is fantastic way to not have enough volume of air get to the FPR so it can not raise fuel pressure 1:1 with boost as needed and blow the engine.The FPR vacuum is ran to one of the 3 throttle body vacuum ports.
