TPI vaccum hookup help - The 1947 - Present Chevrolet & GMC Truck Message Board Network

OK I know there are a hand full of people running TPI mine is running but not yet driven. Anyway where did you pickup vaccum for the power brakes? Also the 400 turbo require one. I have a small one by the fuel pressure regulator that may work for the tranny I thought I had a big one on the drivers side on the plenumn but I dont think it is vaccum? What all did you do?
Thanks
Dave

here's a pic of the brake vacuum line connected at the rear of the driverside of the plenum. the fitting circled in yellow is where it connects. That is the booster line you see connected. I hope this helps.
