OK long story short I am reading boost off gauge witch is installed on back side of intake..I have a large vacuum line coming of rear of driver side valve cover.This line runs across front of intake the leads into a vacuum "T" I believe this "T" is supplied by ATI. This connects to surge valve and fmu. I have no vacuum at the "T" or fmu . please help Is this vacuum line considered part of crank case vent? could i relocate my vacuum line to front of intake without the "T"?

 

Snap a picture.

 

This is the so called "t" it sets on passenger side in front of intake connect to surge valve and fmu.
It runs across frontover to driver side and to back of valve cover by firewall cant get pick of connection but by firewall

 

I also have an ATI Procharger. Forged removed that "T" and replaced it with a vaccuum line distribution block. That "T" was causing me to lose fuel pressure. Give Forged a call.

 

I don't like the sharp angles of those vac lines at all.

 

I used a vac distribution block that I ran my bpv, utec map, and boost gauge from.
Here are some pics on how I ran them:

The line he shows in pic is correct.But my problem is I have no vacuum to the "T".I noticed that my fmu was not lighting up while trying to make adjustment.I have no vacuum to fmu under load.I also have no vacuum at "T" at idle.

 

Try hooking up your vac line to the passenger side front of the plenum where there is a nozzle that extends out. The stock line that should have been removed from that location will then be routed back across the plenum to the larger line that came off the drivers side valve cover ( crankcase vent ). From there you will "T" it and run a open uncaped line into front of the blower. Also make sure all your connections are secure to avoid any leaks. Hope this helps.

 

Just thought i would follow up with a thanks you nailed it !!!

 

I'm glad to hear you got everything squared away. GL with the rest of your project.
