I'm doing away with much of the vacuum related things on my foxbody, and I want to keep many of them capped at the intake to keep clutter down with my GT40 intake.
Can i use the port on the vacuum tee labelled "B/R" (second from the left) to run my MAP sensor? It's originally capped off. I realize that vacuum is vacuum, but I wanted to make sure the MAP sensor isn't going to have trouble because of it. I would normally run a line right up to the sensor from the intake but it only has 3 ports on the back side, and they're all 3/8 line so I'd need a fitting reducer that looks very ugly.

Thank you for your time!

Normally i'd say yes, but with the MAP sensor, you want direct manifold vacuum without running to the tee and branching off

Thanks man. I'll figure something out. I currently have a reducer on the FPR, I suppose I'll run another reducer and try and tuck it under the manifold from the front somehow.

Do you think I could use the same strategy for the FPR instead? Just got to thinking about it

FPR also needs dedicated vac due to risk of pulling fuel in if the regulator leaks.
