FiTech EFI system

problem is I already use a four hole spacer. for fitment issues.. Which probably worsens my situation.

If using both fitech vacuum ports don't work I will drill into the spacer on both sides and then use them both
Hey Ken, I have snooze a bit on this thread but reading through your last Few posts. Does your center divider have an "equalization port" in the divider? Or completely separate dual planes? Or am I misreading entierly?lol Just curious. Your goal is to not only pull vac reference from one bank?
