random hose

[jbeck]

Im almost done with my b16 swap in my 1990 civic hatch. Everything is looking good, all my heater/coolant hoses, as well as my vacuum lines are all hooked up, I was fidling with my exhaust and i found a hose coming out of the firewal on the passenger side almost on the bottom. Its about 1/2-3/4 inch in diameter. I have no idea what this is. I have everything hooked up! Any Ideas.....? Thanks

its pretty small, like 3/4 in. The wall of it is pretty thin and its pretty flimsy. I really dont think its a heater hose, as i have them all hooked up already. any ideas?

Is it orange?
Is it the stock black box(to the left of the fuel filter) drain ?

 

[jbeck]

no its not the orange one, its a black one from the factory. Its wierd, the more i think about it, i dont think it was hooked up to the d15. Im really puzzled. Im fairly positive its not a heater hose, but I really dont know what else it would be, Thanks for the input.

Do you think you could snap a picture?

 

[jbeck]

yea, i will tomorrow, as it is dark now.

 

[jbeck]

ok, its dark and the picture sucks. If this doesnt help ill just do it again tomorrow. Its right below the charcoal canister.

Snap, I don't think you need to worry about that at all.
I wanna say thats a drain for something... dang... I can't remember what it is exactly... sry!

I know for a fact though that it's not needed on the motor, and your not in ANY danger runnin the motor without it.

it is a vent for the air box or cowl

 

[jbeck]

ok, cool thats what I was thinking but I really wasnt sure at all, just let it hang then?
Thanks alot

 

[Andrew]

yep just let it be

that hose is your stock A/C drain. When you use your A/C, the evaporator condensates, it needs a drain, and thats what that is
