I have a aeromotive A1000 fuel injected bypass regulator. What I whant to know is if you hook up the vacum port to a vacum on a NA/N2o enging I was told by a freind that you only hook up the vacum on Forced induction application.

 

What car/engine are you putting this on?

 

I left my regulator vented to atmosphere (N/A application). I wanted steady fuel pressure regardless of manifold pressure.

 

Thats how I want mine I am just making sure it wouldnt cause a fuel pressure drop at high RPM. Thanks.
