Might be the brake vent fix, check out:
http://www.qsl.net/ke6myk/greentruck/m44vent/m44vent.html
from Mark's Green site, it is a reprint of :
Brake vent modification for M44-Series 2.5-Ton 6x6 trucks, from PS Magazine
If it is ...it is a good thing:)
Check out the pics and explanation at Mark Blair's site.
This is how my M35A2 is set up. It seperates the brake vent and the gas tank
vent from the road draft tube and brings the brake vent up into the engine
compartment. If you look at the cap on the end of the line it will have
small holes in it and you will see it is actually a breather.
Anyhow it is all on Marks page.
