Swapping out the Supercharger on my 3800 SC.

The fuel pressure regulator has a vacuum line.

It was attached directly to the old SC, but my new SC has no provision to attach it there.

Can I attach this line to a vacuum/pressure on the lower intake manifold?

This is the same place my boost gauge is connected, so the fuel pressure regulator would see vacuum and pressure. Is that appropriate to its function?

Thanks

The FPR and MAP should be attached to port on LIM under snout.

Yes. It helps equalize fuel flow through the injectors across all load levels.
