elsrr135756 Posted October 2, 2013 Share Posted October 2, 2013 I was working on my 98 subaru legacy today and I was about to put the cover on the throttle body, when I noticed a small vacuum line was disconnected. This vacuum line comes from the pressure exchange solenoid and one end connects to the fuel pressure regulator and goes thru a small filter, but what does the other end connect to - and where is it located?

Fairtax4me Posted October 2, 2013 Share Posted October 2, 2013 Not sure what you mean by pressure exchange solenoid. There is a pressure source switching solenoid on the passenger strut tower. And the Evap purge solenoid under the #3 intake runner. The line with the filter is supposed to go to the switching solenoid, which has a small line that then goes to the MAP sensor right next to it.

elsrr135756 Posted October 4, 2013 Author Share Posted October 4, 2013 finally found where the vacuum line goes - it goes to the intake manifold just below where the vacuum line from the power brake booster connects to the intake manifold Link to comment Share on other sites More sharing options...
