Mustang power rack

I am using a pinto suspension, a chevy power steering pump, and a 94 Mustang steering rack. I wanted to know if I need to use a volume reducer in the newer mustang rack?

I've read post saying that you need to use one on mustang 2 rack but nothing on newer racks.

The reason for using the 94 rack is because it was free and it was wider so I didn't need to expend it to work. Just need to know I need a volume reducer?

Thanks

well, is he trying to reduce pressure OR volume?

my GUESS would be pressure but i could be wrong

if it's pressure, don't get to excited, i've ran my MII rack (used) for many miles with a run-of-the-mill gm (not for r&p) pump.

if you're REALLY worried, grap a pump off an early omni (remember those POS?) or a mopar FWD wih a saginaw pump and use it....


some of you guys really make stuff complicated.... :rolleyes:

After rereading the original post I see he refers to volumn. I'm pretty sure he means pressure as the gm pump puts out I think over 1000 lbs. pressure and the MII rack needs less around 8-900 lbs . Don't qoute me on exact #'s. A search on this forum will turn up a lot of info as this has been discussed many times. :welcome:

Flow Control valve needed

What is needed to connect a GM p/s pump, rated at 3gpm, to a Mustang II rack, using 2 gpm, is a flow control valve. Speedway Motors has them, under $20, when I bought mine. It screws into the back of the p/s pump, replacing the control valve already in use. I have a the same set up and it cured my problem. Problem known as the "twitch" commonly caused by mating a GM pump to a Ford rack.
