Unfortunately you have just scratched the surface of how difficult it is to work on a HMMWV.
I do not see that box referenced to a HMMWV, not all H1 Hummer parts fit the military trucks, it might but you need to double check before spending money.
And like you said it might be a hose.....
I found a cross reference to a Cardone 27-7595
EDIT, that was not the right number at Summit
Sorry, that number does not look good on the Cordone site, it was crossed referenced on a GP site.
Back to the drawing board......
