Question - Looking for Thread on a Pressure tube Fitting causing Low Mileage

[skypilot]

Am now getting terrible fuel mileage -- was getting close to 17, 17.5 , and now in the low 13s if that good.

I seem to recall seeing a thread here back in the summer where someone had found a 'pressure tube fitting' that was coming loose just south of the turbo -- As I recollect it was mentioned that the best way to get to it was by removing the right front tire, then the internal fender well covering.

I've done several searches but have found nothing that matches -- in fact as I'm thinking about it there were also some pictures of it posted as I recall.

Any help is sincerely appreciated.

GH: Thanks -- that is exactly what I needed. I had my truck into the shop and they replaced some pipe can cover as the cover had 'melted' to the pipe. Seemed to fix the problem but it is now back again after about 2500 miles pulling a 12K 5th wheel. Now to take pictures and description and see if it is the same thing.

Again, appreciate the help.
