vacuum line issue

[webemj65]

there is a vacuum line that comes up from under the surge tank and then tees. One goes to the passenger side and the other? does anyone know where the line may plug into....?

Probably goes to your hubs for the auto locking feature. Are your hubs working properly.

man i wish you were right. I thought the same but traced those lines and they are tied into where the tee is. the hub lines go across the rad to the right side and then drop down to be teed off by the axle. i also thought they may opperate the heater control but everything works fine. it a mystery.

here is a picture of the vacuum line. I just cant seem to figure out where it goes and if it is routed correctly. I know the t has to be in that general area. i just dont know where it may go.

That T goes to the Vacuum pump, Vacuum res., and over to the passenger side for the 4X4 actuator.

where is the vacuum res. located. on the drivers side? thanks guys, you have been a huge help!

[greasltn]

The vacuum res. is the bottom half of the degas bottle. Some people have added accessories to the truck and screwed fittings to the degas mount and caused vacuum leaks.
