gmrulz4u Posted June 21, 2003 Report Share Posted June 21, 2003 Does anyone know where I can get a hold of a diagram that shows ALL Vacuum inputs and outputs, in other words a COMPLETE diagram? The stupid AllDataDiy.com and Chilton manuals only show you the Vacuum as it relates to all the Emissions related components!? So basically all it shows is the 4 Throttle Body Vacuum lines, and where they go, such as PCV, EGR, EVAP, MAP, Fuel Pressure Reg., and that's about it! I figure there HAS to be more than just this when it comes to vacuum!! Such as the transmissions vacuum modulator etc... Anyone? THANKS! PS I am referring to the 2.8/3.1 MPFI engines:) Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted June 21, 2003 Report Share Posted June 21, 2003 yeah, the tranny has a vacuum line. Its come out of the plenum, the metal line that screws into the plenum right beside the TB. That line runs directly to the modulator. Well, theres the brake booster line, coming out of the rear of the plenum. I think thats about it, though. I just had mine apart, and dont remeber any others. Robby Quote Link to comment Share on other sites More sharing options...
