Hmmm...air leak.

[dhirocz]

Ok so I'm getting annoyed here.

I have a bunch of small air leaks. I'm taking the truck with me to the hose shop when I go home on my 34, in order to get some of these fixed, and I will just remove and replace the leaking fittings on site...

However, I have found that I cannot find my air check valves to save my life. Every schematic I have found puts them on the inlet of my primary and secondary tanks. In fact, the system isn't even plumbed the same as every schematic I've seen.

I know that the primary tank is the one that will not hold pressure at all when the supply tank is vented. The secondary tank holds, though not well. I considered the possibility that someone removed them entirely, but then I would expect the secondary to bleed down immediately like the primary. I think the check valves are elsewhere, and I'm just not seeing them though I've already looked twice.

My local dealer has not been able to help me with an air brake schematic of my truck. Anyone know of an online resource that would have KW schematics like these?
