Power Steering Rack -AN Adapter

[96Turbo]

hey y'all. I've been having a bitch of a problem with my stainless braided hi pressure PS line.

I've made the line correctly (doesn't leak), and bought what i thought were the right fittings.

My fitting on the Pump (16mm x 1.50) with a copper crush washer seals beautifully.

THE PROBLEM:

I can't get the damn adapter on the rack (14mm x 1.50) to seal for shit. I've tried:

1. Earl's O ring fitting (aluminum)
2. " " With crush washer #1 (wide sucker)
3. " " With crush washer #2 (skinny sucker similar to the one used on pump)
4. " " Russell O ring fitting (steel)(longer tapered section which i thought would press the o ring in to seal)

They all leak! I haven't tried any crush washer with the russell...but i doubt that'll do anything

I've tightened the fuck out of both fittings (all my strength on a box end wrench) and it leaks out from the adapter. any suggestions?

get a different fitting, I have this one and have been running it for almost a year with no leaks at all summitracing.com (http://store.summitracing.com/egnsearch.asp?Ntk=KeywordSearch&DDS=1&Ntt=RUS%2D670520&x=24&y=5&N=700+115&searchinresults=false)

This is the one you need RUS-670520 (http://store.summitracing.com/partdetail.asp?autofilter=1&part=RUS%2D670520&N=700+0&autoview=sku), ive been using it for almost a year with no leaks or problems.

thread sealant! :rofl: look at the packaging, there should be one that says its for power steering, its in a small white tube

my cousin and I went through the same deal hahaha

edit: is your fitting leaking on the racks high pressure line? or the fitting for the return line to the reservoir

here are the 3 fittings that I remember

high pressure pump fitting: crush washer

high pressure rack fitting: nothing and no leaks :wtf:

return line rack fitting:

o-rings = leak
2 different crush washers = leak
thread sealant = good

sorry for getting a little off topic, but i am gonna be putting power steering back on my car in the near future with braided lines like you guys, but i just have one question, is this wire plug/connector in the pic below important? what's its purpose and where does it go on the harness? how are you guys doing your ss lines with that plug?

we just got rid of it

DJ something talks about it in his thread either on here or nico
but it does something like raise your idle at full lock

someone with more information could chime in but from what I recall, it does something like that and that it's not needed

i was told it was a temp sensor...but ive run my s13 wihtout it with no problem for liek a year or so...

[96Turbo]

naw, it's a pressure sensor. when you turn to full lock, the pressure becomes much higher and strains the pump (thus straining the engine) which is why you can hear it struggle at full lock.

so the pressure sensor anticipates this and kicks up idle a bit to compensate. For the brief time i've run without it, it doesn't seem to make much difference.


As for the link to the summit adapter you showed me, it's basically the same as the two i've tried, it just doesn't have an o ring. the Earl's adapter was basically non o ring anyways since it wasn't long enough.

But maybe i'll try the thread sealant trick....

i'm talking about the high pressure line on the rack...not return line. I'm using the stock return with the oring fitting. seals fine, but it surprises me it would even leak since it's not hi pressure.

but hopefully thread sealant will fix my hi pressure line as well

That's correct. When steering pressure increases during idling, the idle is raised slightly.

If you don't have the sensor, the engine may stumble a bit.

Is it needed? That depends on you. Are you sensitive to noise, vibration, and harness? If you are, you shouldn't be in an S-chassis :)

But it doesn't hurt anything to leave the switch out.
