aha rebuild

[Bill Shaw]

The fitting stuck in the end has the same part number as some other hard 
lines under the hood,  and it's flared a little at both ends.  Looks 
like a connector made out of the same hard tube used elsewhere. 

Looking under the hood again,  I found a hose going nowhere (part of the 
canister purge circuit?) ,  and the 374-b hose fits nicely.  I still 
don't find where the other end should fit though.

I took another pic:

The 374-b hose is circled in red.  It's plugged into a short twisted 
hose that's 'T'ed into the hose that runs straight across the back of 
the bay (marked in yellow).  I'm not sure it goes there but seems to lay 
in there OK,  just have nothing to plug the other end into.

And thanks for all the input guys,  I really appreciate all the comments.
