    No bueno

    So there has been this puddle forming in my back seat and hasn't stopped. I assumed it was coming from the back (bad assumption) it's coming from a broken ac line under my dash near my ecu. Anyone know where its supposed to connect to? There is a small hole in the firewall it fits, but im not sure if it's just supposed to be pushed through or something. I'm really lucky my ecu isn't fried. Please can anyone help?

    Its seems like you're in luck. That's not an A/C line. That's a drain line. Go on the motor's side of the firewall and look to the left of the downpipe. There should be more of that rubber tubing there, pointing down.

    Non-Subaru downpipes sometimes melt the external portion of the tubing. Yours seems to have problems on the inside. I've not seen it before on Imprezas, but it does happen.

    EDIT: If you're asking where it connects on the inside, look for a "nipple" on the black plastic "basin" housing on the outside of the HVAC unit behind and below the glove compartment.

    Does the amp get hot? It'd probably be worthwhile to figure out why the tubing failed. It can melt when exposed to heat (as shown by the melting due to downpipes on the "outside") but why did it fail on the inside? Did something rub against it? Did something heat it up?

    My guess is that when the downpipe was installed someone cut it too short and it worked its way inside. It should go through the hole in the firewall you mentioned, push it back through and secure it somehow so it doesn't come in again.

    It looks like the inside fitting has come off, or the inside portion of the pipe is cut because the length left points toward the console and the loose end is under where the inside fitting should be. The OP will have to check which end is loose though, you are right.

    Well I looked and there was no tubing near the firewall in the engine bay. Does the tube feed through the firewall like this?

    Because if it does im sure the dp melted it. There is no loose tubing anywhere in the area

    Exactly like that, yes. Mycologist was correct.

    Figure out a way to keep the tube there and prevent it from backing out again.

    Thanks again for the quick response's, y'all are the ****. Nothing a lil duck tape couldn't fix. So will that tube melt from the dp, or does it have a high temperature rating? If not I'll replace it with something more durable, that can take the heat.

    Or possibly replace the tube so it is the correct length, then there are a number of ways to fasten it out of the way without crimping it. Mine goes off to the right (passenger's side) and is zip tied. BTW, do have a turbo heat shield? Good thing to get if not.

    It will melt if touching, but mine has only ~1/2 inch clearance and is doing fine for over a year.

    No i dont have a heat shield, where does that line lead to exactly? Does it just drain to the ground or does it connect to something else?

    Edit - Sorry didnt see it close enough it just drains to the ground right?

    Yeah, it should go to the ground. I have seen some that are just pushed over onto that rail, but it will puddle there and I can't tolerate that.

    Sweet, thanks again I'll probably end up getting some neoprene hose to replace it.

    You'll have a lot more room - mine is DWG and it sticks over further, plus it flares out for the cat.
