this hose comes off the top steel vacuum line setup pictured. i looked for something near for it to connect to and didn't see anything. am i blind and just don't see where it connects or should it be longer and connect somewhere farther away? this area is the vacuum hose cluster near the fuel inlet line area. any ideas? thanks.
yes; it's the one you marked "This One". i should have mentioned no codes in my original post. just went and checked for vacuum...none (at least while engine is still cold and hasn't run long enough to warm up...i'll check again tomorrow after it's run enough to warm up and report back).
back in 2005 (at ~110k miles with ~ 180k miles now), a new EGR solenoid and BPT valve were put on by the dealer. yeah, that ridged od hose is oddball looking (only one i've seen like that on there so far) and is routed kinda meanderingly around.
Here is shot straight down at mine. Hope this helps.

from spark1562's pic and trini boom's insight, and the fact that the unconnected hose has no vacuum on it, i'm guessing that when the dealer changed the egr valve, they found no vacuum on the original hose & connected the ridged od hose (from who knows where) to bring vacuum to the egr valve. when i'm changing the valve cover gaskets and cleaning the egr tube, iacv & etc. sometime over the next few weeks, i'll locate where the ridged od hose goes, try to determine why original hose has no vacuum and attempt to repair & reconnect original hose to egr valve if possible. thanks everyone.
