Use a 14mm crows foot^^ worked wonders!!

I had put in power steering fluid not even looking at the cap. It takes Dextron ATF. I bought some and disconnected the pressure line underneath and the reservoir line down low. Drained, reconnected the lines and refilled. As I was bleeding I noticed some drips on the ground. After wiping and rebleeding, I find a leak coming from a line I never touch



It was leaking from between the line and fitting. I pulled the line off after dropping the crossmember. One of the flares is smashed ??? I thought it was tight, maybe too tight and noticed this when I backed out of the bay.


The line


Good double flare


Smashed flare, see how flat the side edge is instead of having a mm or so side?


I talked to my dude at a Subaru dealership that has a few donor cars and he's going to pull one off another Sti for me. I'm picking it up Tuesday.

For anyone planning on swapping both lines going to the rack.... .

I found that removing the brace that covers the rack allows you to move the lines a bit more to make them easier to access. Especially the return line that has the rubber hose in it.

[Ishart]

Also. There is a a sort of "restrictor" pill in the line. I cut my open just out of curiosity. I have pics for reference if anyone is interested.

[scby rex]

theres pics of it in the first few pages. It doesnt do anything and your fine without one.

He also stated that the 9894DBH adapter that we are all using is not correct for the application and that it needs to have a 70-45* bevel cut inside in order to accept the flare fitting on the rack side.

as it stands you are essentially crushing the flare and hoping it holds the pressure.

So there isn't a correct fitting to replace the 9894DBH ??

No,
He informed me that we should cut off the OEM fitting and braze/weld on a AN based fitting. They offer the weld-on fittings.

The other alternative is to machine in a bevel to the 9894DBH this would help mate up to the OEM line.

There are companies that make them. They are not cheap. See this:

The problem with what you're saying jnorth85 is that perhaps your setup is different or maybe I misunderstand, but my rack doesn't have a flare fitting. Instead it relies on a oring to seal on a flat surface inside of the fitting. I can verify this by looking on the inside the factory lines which don't have a flare fitting on them.

Here is a picture of the high pressure side on the factory line (sorry for the bad picture, cellphones are poor for shots like these):


Here is a picture of the low pressure side on the factory line:


Essentially they are both the same but with different diameters. No flare there. Now look at the rack side fittings:






See the oring seal? No AN flare fittings on this one. At least on the 06 WRX rack I have.

The only modification I would do on these fittings from EARLS is to cut a slight chamfer on the inner diameter of the fitting to resemble the stock fitting and be a bit easier on the oring. That's my plan. But the lines are certainly not a reverse female flare fitting.

Yes that.
You can easily modify the earls fitting

See above. There is not need to modify it like you are describing.


EDIT: OK, I think I was just confused on what you said at first. We are saying the same thing, but with different terminology. I hear flare and start thinking you're talking about a 45 or 37 degree internal female flare like the fitting I posted above. :facepalm: You are correct.

You are correct, the chamfer is NOT hard to add to the inside to mimic the factory lines and I had already planned on doing that.

Apparently you are cool without it though as everyone here has been doing it for years! Maybe they just have slow leaks or always air in the system.

Yup exactly! That's also what I plan on doing. From what Tom at earls told me it will hold but at a much lower pressure. He said if you were to smack a curb or introduce a shock load it would blow the fitting out, in addition once its cranked on you can't really remove it again.

What about re flaring the power steering lines with this tool. It says in the description that this make 37 degree flaring for AN fittings.

you could the motor in the car there isnt much room with the rack installed, also the lines coming out of the rack arent very long to begin with.

I have this tool and had a tough time flaring good grade aluminum lines. I can't imagine how this could possibly work on a oem hard line.

The problem is the little holder bracket can't hold the line unless you put an ungodly amount of torque on the nuts. Otherwise the flare part of the tool just pushes the line through the holder. I had to a big ass adjustable wrench on the nuts to stop it from slipping

[Bad Noodle]

Can any of these lines (FMS, P&L, Chasebay) be routed like like the stock line but with a little more slack. So it lays on the frame and goes by the PS bottle?

(I looked for install pics but couldn't find anything)

[scby rex]

I made my own like that.
