I actually have a few questions on some vacuum line routing. I watched a couple of videos but all the videos still have the air box in there and the black clip with the hard pipe that runs to the air box and other places. my vacuum ball isn't in the same place as the videos and there are no vacuum lines hooked up to my EGR sensor or the EGR valve and there is no vacuum line hooked up to my fuel pressure regulator. The vacuum line for my map sensor is hooked up but according to the videos I looked at it's hooked up in a different place. I would sure appreciate some help with that or maybe a link to a good vacuum line diagram. It fires up and runs and according to the guy I bought it from he drove it the way it is for 2 years so I'm not sure if I should start messing with it or not. The guy I bought it from is a head mechanic at a shop in Georgia but that doesn't mean he always knows what he's doing. Thanks again guys

Also I don't know if that air box being gone and that air-to-air hard pipe on top being gone have anything to do with the change of the routing for the vacuum lines or not
