Small dillemia. FINALLY getting my 1999 Subaru back togther after doing a full maintinance on the EJ22E.  The Engine is in, and I'm starting to hook up the engine. I came across the  little vac port that is on the back of the fuel injector rail opposite side of the starter.. Where does it hook up to?. I know the line with the filter in it goes to the port on the intake.. The port line that goes to the cruise control actuator is also dangling, but I don't think I disconnected that.

The vacuum line to the FPR is T'd off to the MAP sensor on the passenger strut tower, if it has it, and the vacuum port on the number 3 intake runner.

 

Cruise has its own vacuum pump down below the AC accumulator on the passenger strut tower. That system isn't connected to the engine at all except for the throttle actuator cable.

Thanks. I thought it was a Tee'd line. I now remember cutting the line away and breaking the Tee pulling the lines apart when I removed the intake before pulling the EJ25D.. Now I just have to remember to buy a new Tee.. I thought I was one port short to have the cruise hooked up. I'll have to check for the pump but I have to assume it's broken as it was disconnected before I started
