Power Steering Question I have a LS2 with a Mustang II rack. What are people doing for the pressure line. I have tried to have a line made but none of the shops make steering hoses. I have the factory line, I just need to change the 1 end to a 5/16 o-ring fitting. Does anyone know where I can buy this fitting. I see some fittings on Speedway to adapt the pump and rack to an-6 fittings. Then I still have to have a line made. Has anyone used these fittings and did they work well.
Thanks Terry

you can call Jegs, or Summit. Or go to your local speed shop, tell them what you need to do and they will know the components you need.
I went to my local speed shop and was given the right parts within a few minutes.

If you haven't already, be prepared to shim that pump output or put an inline valve like the one Heidt's sells. The GM pumps put out WAY too much pressure for a MII rack, making the steering very twitchy! Undriveable, by most accounts. I've shimmed my pump with the kit Borgeson sells ($20) based on other's experiences.
Lots of discussion on this topic over at hotrodders.com, btw.

You can build your own line, I did on my swap. Jut be sure and use SS fittings and teflon lined SS hose for the HP line. Use steel adapters if at all possible, and do as Richard said on the flow reducer. This goes in the rear of the pump and will make your combo much more livable...

I had a hydraulic shop make up my hose for $40. I have an 01 Mustang and I did not use a flow reducer and I haven't had any problems with it being twitchy. Not saying you don't need one, I may add one yet.

I decided I needed the flow valve when I was bleeding the system, front wheels off the ground. As soon as I crossed the center, the steering wheel started shaking violently back and forth and would only stop when I killed the engine. 
Might not have happened would I had done it with the wheels grounded, but it was definitely an eye opener!

After searching the internet, i found that russell fittings makes the fittings that i need. # 648010 and 648060. I'm going to have a hyd. shop make me a hose using an-6 fittings. Thanks for the sugestions.
The later Mustang racks have a higher operating pressure than the Mustang II racks. I just picked up a 1990 Mustang power rack today to help avoid some of these issues. You might still need to "fine tune" it but you don't have to overcome a 500psi overpressure like you do with the Mustang II racks.

Mine feels pretty good so I'll probably just leave it alone.
