Return PolicyIt is common to use an early GM power steering pump with a Mustang II power rack and pinion. Most who have tried it have found that the steering was twitchy or that it easily darts. This valve will replace the existing fitting in the back of the early GM power steering pump and reduces the fluid flow from three gallons-per-minute to two gallons-per-minute, which cures the problem. For applications using the O-ring style power steering hoses (use in conjunction with adapter insert # 910-32921 for inverted flare hose application). Installs in the back side of the pump (see above illustration pictures).
If converting pump from modern 16mm o-ring to traditional 5/8" inverted flare style hoses and utilizing this pressure reducer adapter fitting, use this fitting in conjunction with the following adapter insert and order (1) Adapter Insert 910-32921.

Troubled Steering
I had a terrible problem with my 53 Chev truck darting after installing mustang II and power steering. This valve solved all the problems. I feel like I'm driving a new car. Major improvement.

I don't know, maybe it's me..............
I didn't like the way the steering responded with the shim set, used 3 shims for the Mustang 2, as per directions, it was still over sensitive. So I bought this on their recommendation and the response is the same. It was a pain in the a-- to get the pump out and back in twice. I going to have to take my chances with it as is till I find a better solution. Will have to find a Ford pump, and adapt it. But for the time being I very disappointed in both products.....Joe

The flow valve fit great. I installed it, drove locally about 20 miles. Then just got back from a 668 mile road trip. Worked great, no leaks.

Thai valve slowed the power R n P (89 thunderbird rack) down in my IFS 1950 Chevy truck. The Saginaw PS pump was putting out way too much pressure and the truck was all over the road. This made driving it much more enjoyable and safer.

This reduced the twitchiness in my steering. I have a rebuilt Saginaw gear box and power steering pump on my Chevy engine (olds 78 Cutlass). For some reason the steering was twitchy from the beginning. I am working through this but don't know why this is as it is.
Would Recommend
I would definitely buy this again.

This fixed the problem. I have a Mustang ll 1978 rack and pinion with a gm type 1 pump. After a lot of research I found that this is what I needed. You have to reduce the pressure and the flow. I installed the borgeson pressure reducing kit. It called for 3 shims to reduce it to 1.000psi. I installed 4 shims reducing it to 850psi. Then I installed this universal control valve for type l and type ll gm pumps. Speedway is the only place i could find one for type 1 and type ll pumps. Problem solved! I have great road feel at high speeds now. (Install both) I wrote this review to save you all the trouble and research that I went through.

Hi, Can you confirm me if I buy this part and the hose kit 91032530, I will have all the needed parts to connect my chevy steering pump to my Mustang II powered steering ? All the fittings will be good ? Do I need the adapter 91032921 (my pump is a new one placed by the engine builder and I don't know the model but I can send you a picture by email) ? Thanks a lot, Math,
