RB26 Balance Tube - Cut to Pieces

The balance tube is hidden under the black plastic channel for injector wiring. 

The balance tube in an RB26 is connected to the plenum on an RB26, and carries vacuum and water. It houses the 10mm air bleeder, and it has a provision for the PCV.   In addition the vacuum/boost source for the FPR and the map sensor for the gage is driven from the common vacuum. 

This is the front. That small tube in the front drives the fuel pressure regulator
