Nice, what did You do with the Pumpers?? Yeah, the plastic vacuum/pressure reference lines & distribution setups were an abortion in general, the problem was the Tees
had the calibrated restriction orifices in them, color coded, so You needed to re-use/replace them unless You duplicated them w/metal jets.......................
Oh Yeah, We were putting plastic vacuum tees in with the paint can spray nozzles jammed in them at the MAP sensor on those old logic modules, per the TSB for moisture
(condensation) settling in the long line from the engine inside to the MAP,......then freezing when it got cold.........................................
