So in terms of o-rings, bought some 1.5mm wide x 6mm ID and 8mm ID o-rings from mcmaster. They seem very close to OEM





The only issue I ran into is that for the return line, it needs a 16mm x 1.5 to 6an adapter. But the fitting female end is too long for the OEM nut. A test fit showed that with the nut bottomed out in the fitting, I can move the combo around the flare. The fitting is 12mm deep while the OEM and nut is 10mm. The high pressure side fitting is 10mm deep as is the oem. For reference:



So what should I do here? Hacksaw/dremmel 2mm of the back end of the fitting? What have you guys done?

Doesn't look like they will snag anything but would consider some heat retention as the dp will be pretty close to those power steering lines and wiring.

Fire shield for the ss lines, and get the nifty Velcro heat sleeve from summit or dei for the main engine harness if you don't feel like fabbing up a heat shield.

^ either that ^ or do what I did in both my cars and bend the PS wrack hard lines a little so they are more pointing straight up/toward the bell housing and run the lines under the intake manifold right to the PS pump. Then your not smack up against the UP and cooking the PS fluid.

It will be fine. I didn't go fancy like you. I only used SS on the high pressure side. Seemed like a lot of work to change it over to SS on the low pressure side. But it does look purdy

This is from my build thread. It shows how I routed it. BTW I am rotated so keep that in mind.

This AN fitting goes on the pump:


Here is the SS line attached:


To get at the fittings by the crossmember, at a minimum you need to removed the turbo. Since the turbo is rotated, and the downpipe is v-band, it's a relatively quick procedure. Plus I've now done it several times so I can knock it out relatively quick.


Here you can see my up pipe. It's been wrapped with DEI Titanium, then on top of that I used some aluminum tape, then wire wrapped the aluminum tape. I think it was Suicidal Eggroll that posted this method. It works great at not soaking up oil, etc. I learned my lesson after soaking my up pipe on install. You can see the blue AN adapter connecting to the power steering line.


Here it is connected:


I also replaced the low pressure line with 3/8" fuel injection hose. I don't trust clamps that only use spring tension, so I put a T clamp on it.


Here are both lines coming up next to the up pipe. I put a heat shield on the high pressure line since it's close to the up pipe.


The low pressure line hooked up to the reservoir. Here I used the spring clamp mainly because if it is leaking I can quickly change it to a T clamp.:


Another shot of the low pressure line. I have it zip tied to the brake line:

It's gonna be a pain fixing these when they leak. And they will leak. I'm used to the good-ol AN / NPT type mechanical seal. These didn't feel like that. They just bottomed out and that was that...

Hey that looks good! Mine haven't leaked in over 12k miles (cross my fingers)

as long as you have cleaned the surface and properly used a crushwasher, then fully tightened - the fittings are unlikely to leak

Has anyone had an issue like this? On my track car with one of these setups, when the car heats up I lose power steering-- its gradual, the tighter the turn the less the power steering works. No leaks, no bubbles in reservoir.

Ill have to get a pic of what I did. But I took my stock line to a local house place and the cut it and crimped a -6 fitting onto it. That way I need the factory connection at the rack connection.

I would save yourself the trouble and buy a kit but if you really want to build it this thread has everything you need.

I am in the process of doing this now. I have a forge motorsport aluminum tank I want to mount it somewhere tucked but in a clean way. I used to have it mounted on the passenger side up high, near the factory boost control. Anybody have any tips on where to mount it? Somebody told me I mounted it a little high. I am keeping the left and right side of the engine bay empty.

If its lower then the PS-pump be sure its sealed and never closer then an inch or so from the top for expansion and froth up

If its above the PS-pump just keeping it full is all you need to know..... Id still make it sealed.

I have always wanted to put it in the wiper cowl with a round cut out access in the cowl and a nice threaded cap....so the lines will go through the fire wall into the cowl. That spot is a empty space asking to be filled with necessary but hidden bit removed from the engine bay

Funny you said that I was thinking the same thing. Perfect if that made it in the shaved and wire tucked thread.

I just tried it would require a lot of work or a smaller tank, my tank has two nipples on the bottom.

im in the process of replacing my high pressure power steering line with a braided one, i bought the inverted flare fitting for my steering rack. from my understanding some fittings utilize the seal, and other fittings do not use the seal going off the steering rack. Im just wondering because I'm only looking to do this once. here is the fitting i have……

seal, or no seal?

The pic's you linked are basically standard flare fittings = No O-ring They can be used but with alot of extra work

The ends/fittings coming directly off the rack hard lines are male and have O-rings in them see post 276, so you need female O-ring type fittings, unless you cut the hardlines and hand flare them with female flare ends to accept the flare fittings you linked to.....that is lots of work and hand flaring is tuff along with there is only enough length on the rack hard lines for maybe 1 re-do.

Get the fittings Bad Noodle used or one of the SS/braided kits on eBay for under $80 ( search "wrx power steering line" ) there will only be 20-30 hits and probably 2-4 SS line kits in that ,some kits have separate fittings others have the fittings pressed onto the line.

ah man i was under the impression that the flared fitting was going to mate up to the racks hardline better than the traditional earl fitting, but it seems like I'm in the wrong ball park. looks like i might be doing this more than once.
