Default Need help with power rack and pinion hoses

What size are the end fittings at pump and at the rack?
Also will I need a flow control valve to reduce the pressure?
I would like to make up a set out of braided hose, has any
body else gone this route, if so where did you buy your
materials?

Thanks for your help.

Riggs.

I had to go to a Napa in the area that still makes hoses. It was pretty hard to find a place that still made hoses. Anyway, if you know what kind of rack you have, Grand Am for example, when you find a place that makes hoses you can tell them it is a GA rack and you need custom hoses. They should be able to pull a GA hose and check the ends for the correct fittings.

Sorry I can't help on fitting sizes man, but I installed my systems with junkyard hoses....all I did was cut end and splice together with the correct pump fitting using a 3/8 brass compression fitting...been there since '02... driven daily...

I went to a hose shop... they told me that the type of fitting is very hard to find. They didnt even have it. They said to go to a junk yard and get the stock hoses and they might be able to use those.
Still running no power steering pump on mine and love it.

Come think of it, there is a industrial hose supply company nearby...they can make anything....maybe look up who is around, and go junkyard for the fittings they can match up...thing is, hose shops have NO idea as to what you need/want....without having the car on hand...

I would like one of my hoses there to be maybe 4" shorter, but not going to go crazy over it, they are modified junkyard hoses...

I believe I have found through my searching that the
power steering pump thread size is 3/8'' npt. I still need
to know what the size is on the grand am rack, I think it
is a 6AN thread, does anybody know if this is true?

Thank for any help,
Riggs

Hey Vette427 sbc, with you running no pump how
did you get the fluid into the rack, and how did you
tell if it was full of fluid and with no air in the system.
All the fluid has been pushed out of the rack while I
have been mocking up the setup for my brackets and
tie rods.

Thanks for any help,

Riggs.

The rack will still retain fluid even after moving it from lock to lock. you can just add fluid through the pressure lines while slowly turning the wheel back and forth

you should read some of the rack and pinion posts by Jim Shea on the flow control valves..from what i recall its really the valve inside the rack that makes all the difference.

Does anybody know what size threads are in the Grand Am rack
in both the supply and return hoses? This would be very helpful
as I am trying to buy a set from one of our vendors, and want to
be sure before I buy them.

Thanks,

Riggs.
