Tractor/ trailer over night lose of air?

So it's not leaking down over night? Only when the truck is running?

I have this one. Not cheap, think I paid over $500 a few years ago.
I can find any air leak in under 20 minutes using it.
Even ones I can’t hear, once I lock in on the location, it makes it sound like you cut the valve stem off a tire.

 

Well, here's one for the books. I lost air in my truck all the time and could never find it then a mechanic told me something to try. I backed my truck down a boat launching ramp and found my leak in 2 minutes.

 

That works for air lines to ?

 

You also ruined your rear ends if you didn't immediately drain and flush them.

 

No, ran over 10 years with no problems. Sold the truck and it's still in service today.

 

Then you made up that story. Which I initially first thought till I remembered watching a guy wash his car with buckets he filled in the gulf.

 

I was under impression that you ordered this option when you was building your truck for the whole week with the sales person .

 

Look for my comment #7 here. I fix all my leaks. It’s not hard.

Going hunting for air leaks need advice
