Hey guys, I'm just planning my PCV and evap system in my L92 swap. Is it absolutely necessary to run the evap lines on the intake to the fuel tank, even though my swap tank has a vent already?
Also, is the evap line in the L92 truck intake just a vacuum line? I have a vacuum gauge in my car, and this would be an easy place to hook it up if possible.
Thoughts?
Thanks

Yes you can use the evap line as a vacuum gauge source.

I just tried hooking up my evap line to a vacuum gauge, and it doesn't seem like it has any vacuum (when the engine is running). There is a sensor or connection that I am not using on my swap, and I was wondering if that could be shutting off the vacuum source.
The engine runs great, but I'm wondering if it might have a small vacuum leak because when I stab the throttle, it doesn't come back down to idle immediately. Is this normal?
Its not throwing any codes or anything, and seems to be running great.
Ideas?
