The factory plastic lines are known to get brittle over the years - most people just tear them all out and replace them with regular old inexpensive vacuum line from your nearest autoparts place.

Well the ses light came on today with a1191 code x2 so now it's hunt down where the leak is, and tips. And is there any way if possible to plug the hole where the black tube comes of the air duck and runs in front of the engine bay? I believe it's for expansion air or some thing for the turbo but I see many of the 6.5s with out them

Yes but in it's use it is a barometric sensor-not connected to the manifold.

Yes,usually the baro sensor on the firewall only reads ambient pressure and the one on the intake reads manifold absolute pressure MAP.
In some cases the on gassers the map gives the baro reading during the gauge check and then map when running.

I switched the vac lines the way they where routed originally and now no smoke and no codes. Now that I got that all figured out I'm thinking of redeleting the egr. Thank you all so much for your help. The truck is running like a champ now, and I went from 380 miles to a full tank to 250 miles and I'm not even to 3/4s of a tank
