I have a 1999 Honda Civic with a hose that is not connected to anything. The hose is boxed in red.


Here's a close up.


I think this (the red arrow at the bottom) is where the hose originates.


I believe it has to do with the air conditioner. It's been weak. I'd like to know what the hose connects to and where it should be connected.

 

in for a answer

i think mine is disconnected to....as i remember seeing that in my engine bay.
ill have too look at it tomrrow

 

i think its for some carbon filter crap its soposed to be like that it ges to a charcoal canister i think i dont know what its for in my hatch i pulled all tha **** out didnt see any difference i also got it now in my coupe

 

Pull it really hard maybe it will come out. LMAO

 

It connects under your battery tray to drain water, or acid away from electrical connections

 

Either that, or it's the drain for the A/C evaporator behind the firewall... same general location. In fact, I kind of think that's what it is. It's why Hondas always have a wet spot under them right there when the AC is running. If it clogs up or gets kinked, you'll get water on the passenger footwell when the AC is running.

 

Where you see the hose is where it belongs. It's part of the EVAP system. What has happened is that the drain joint, which secures the hose to firewall, has broken. It's part #16 in the diagram.

 

Thanks for the responses.
So is the drain joint suppose to be connect to that screw directly above the open ended hose?

 

Yes

 

i thought it was like a drain for the wipers

 

honestly i dont think there is a need to fix it cause it dosent go into the fire wall where the screw is if somthing were attached which it looks like there was but it would still just sit there

 

This is another viable option.

 

had that prob before, but i dont think thats it.

 

I have two Civics and there both hooked up to the fuel filter. It doesn't drain anything, it just holds up a hose line that almost runs parallel to the firewall.

 

would this cause any codes to go off??

mine is the same way..and i have a evap leave cel

 

correctdomodo my brotha. You rock!!

 

Well, what I meant, it just hang off the fuel filter assembly. There is a square notch on the filter assembly and at the end of hose has a square shaped plastic end. It just hangs there. Odd. and no CEL
