So I've removed all emissions and blocked everything off. Now I'm just wondering if it is acceptable to run all my vacuum lines off one source? I'm using the UIM to feed vacuum to my boost gauge, BOV, external wastegate and boost pressure sensor. I wanted it to be simple and clean. Any objections or help will be greatly appreciated. Thanks.

Ummm, it can be done, however if possible I don't like to it can weeken the pressure signal seen at other points, and the more you have connected to the same source the bigger chance of that happening.

dont forget to run vac lines to the pulsation dampener and OMP spyder if u still have it. there should also another nipple between the bottom omp injectors that should be ran to the uim also. thats how i do it.

omp injectors vac lines should go from the oil injectors to a spot before the throttle body.



as for using one source for all those things, i wouldnt do it, especially not sharing the boost pressure sensor line.

I've eliminated OMP and all emissions. I was thinking of finding a second vacuum source for the wastegate and BOV, I'll tee the boost gauge off the boost pressure sensor. If this won't work, does it matter where these parts get vacuum from?

the boost guage and pressure sensor are fine Teed, but id use a seperate line for each of the other things
