Hmmm...air leak.

[dhirocz]

So...I put some dye in my air system, ran the truck then checked for leaks. Found it!

...all 13 of them.

Haven't noticed it as audible because it's been leaking slowly from half of the fittings starting at the dryer. I put the dye in after the dryer, and after running for a day she lit up like a Christmas tree. Followed behind with soapy water, some leaked alot and some I really had to soak and wait to notice it bubble. Guess I'll start with a couple check valves on my primary/secondary tanks, order up an air brake fitting kit and start there.
