To put it back, lube all the rubber seals, push the pipe coupling into the crossover pipe, attach the vacuum hose to the bottom of the pipe, then attach the pipe to the intake manifold (at the driver's side) and then at the passenger side. Tighten the driver's side bolt first, then do the 5 on the passenger side.
