FiTech EFI system

New information on Vacuum port on regulator: ( I think)

I don't think this has been discussed on this forum yet, but I guess recent Throttle bodies are coming out with a vacuum line connected to the throttle body regulator nipple to manifold vacuum. Found this out on the Chevelle site.

"I recommend the use of vacuum on the regulator as it lowers fuel pressure under a low load situation. This will help the EFI adapt to your engine better."

Interesting.. will try it in the spring. And disappointing they aren't notifying all earlier purchasers of this "better" setup.

And seeing I run the FCC, i wonder if the regulator in both the Throttle body and the FCC need a vacuum signal. I have posted the question on the Fitech site.
