Any idea where these 2 go?



This was disconnect, goes all the way back of the truck.

 

Trace them and see.where.they go?
The first one might be the vacuum or vent line to the front hub. Is it twinned with another one running beside it?
The other one... The only things that run to the back would maybe be a vapor or EVAP line that runs back to the module above the fuel tank. Or... Someone once had a compressor up front that ran to load helper airbags in the back.

 

I’ll check tomorrow.

2006 4.6

thanks

 

Look at your underhood VECI sticker
It will show all the vacuum lines and where they go

 

4x4 ?

 

Yes, 4x4 4.6 V8

 

does the 4WD work properly ?

 

There is not a whole lot in that area, vacuum hose wise, (by the ABS HCU brake lines) besides the 4x4 vacuum hose
That vacuum hose, and the ABS wheel speed sensor both go out to the hub, and originate at the top of the inner fender panel / fender apron

 

Some people put differential breather extensions on so they can drive through deeper water. And anything that isn’t factory can be done wrong. You can check by finding the breather tube on the differential and seeing if it goes to the stock location or if it seems to be heading to the front of the truck

 

I followed the hose to the back of the truck
