I found an older post by shoebox stating that all the manifold ports are full vacuum, so i should be able to us the one on that side. Hopefully I'll have the new lines done this week and get to test it out soon.

 

You can use the driver side port. I have my Opti vent systen connected there. I didn’t know you were mounting the outboard regulator on the driver side. I have my Weldon AFPR mounted under the cowl, behind the engine, and I don’t use vacuum compensation.

I run the rails in parallel, to minimize any pressure differences between the first and last injectors on the series rails.

When the engine was built, I kept EGR, AIR, and EVAP systems to meet local visual emissions inspection. The cam was also designed to pass tailpipe emissions, while still making 496 HP on straight motor. As the car became more of a “track car”, I deleted those emissions systems. Currently there are no emissions inspections on pre-1996 models.
