4age in my 85 gts

Line on the left and the line below the FPR is uncapped

Varies a bit with model and market, but this diagram for a USDM GTS
suggests that you got a three tittie vacuum fitting that had one hose for
the FPR and the other two outlets were capped off.



Markets with MAP sensored engines typically got a second hose for the MAP
sensor and one capped outlet.
