Ported vacuum source

Anyone know if or where a ported vacuum source exists on TPI motors?

Re: Ported vacuum source

Any of the vacuum ports in the back for the fuel pressure regulator, the a/c and cruise control, or the brake booster?

You can T into the a/c and cruise control vacuum ports fairly easily.

Re: Ported vacuum source

i hate cruise control, hahaham its like that scenerio when the cars come alive and take humans life. I had a cruise control seize up out of the blue. kept increasing my speed on a 35mph zone to 65-70mph. i have it disconnected ever since. even the previous owner warned about it, but i didnt believe him. i got cruise control still installed but i just removed the linkage. considering your Vacuum REZ is in the bumper, i recommend doing a T-fitting and using a check valve rite by it. PEACE

None of those are "ported" vacuum. I don't think there are any on TPI.
