Finally had time to look at the truck today.
Checked the unloader. Removed and cleaned it. No go.
Removed the outlet line and had air flow.
Hooked up an air tank to the Service Valve, no leaks there. Didn't check the emergeny line.....
Crawled under the truck to check for any loose lines. Nothing.
Finally fired up the truuck and crawled under it.
I felt some thing on the side of my head as I was moving into posistion to check the airtanks. Thought it was the 35+mph winds we where having today.
Nope
It was air from the tank bleeder line that runs under the side step. The line had split.
Done know how it split but it was on the side of the line. The air pressure had stop building last fall so no ice buildup.
Robbed a piece of line from my parts Deuce, bought some new ferrels and I am back in action.
So boys and girls, check your lines for leaks and NEVER use copper for brake lines!!!!
