I was recently replacing coolant hoses in my 91 LX, and I wanted to share a nice source for the little hose the goes between the heater core, and the heater core valve; and the hose that goes between the intake manifold and the engine. Both these hoses are illustrated by the green arrows in the picture. I found that bulk hose would not make the bends, and these hoses weren't easily available from Honda (super duper long backorder.) The folks at my local CarQuest found a single fitted hose that when cut could supply both hoses. Its CarQuest hose #18850. I thought I would make others aware of this just in case they're looking for these hoses. I hope this is helpful to someone.
(I have no business affiliation with CarQuest, nor do I work for them.)
