Q & A

What's in the Box

It 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 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. Installs in the back side of the pump as shown in the extra photos.

If converting pump from modern 16mm o-ring to traditional 5/8" inverted flare style hoses, order (1) Adapter Insert 910-32921.

The Mustang II flow valve does work on many GM pumps. If your pressure line goes to a large serrated looking nut on the rear of the pump then you should be able to remove this fitting and install the flow valve in it’s place. If your line is O-ring seal then it will go right in but if it has inverted flare then you will also need the flare adapter 91032921.

Effect on stock GM system? I'd like to reduce the power steering assist on my 1993 civilian Caprice. Will this fit my stock pump and line, and make a noticeable difference? I'm not looking for a Vega manual box feel, but I'm not a fan of being able to spin the wheel from lock to lock with one finger. Thanks.

This flow valve is for the GM Saginaw style pumps and is 16mm. It also works on many of the later year GM pumps including the remote reservoir pumps such as our number 91032906. It replaces the original flow valve which is located where the pressure line hooks to the pump. The new flow valve is set up for O-ring seal and if you have inverted flare on your line then the adapter number 91032921 would also be needed. It will make you power assist much less than with the stock flow valve and could give you the feel you are after.

This will not work well if using the power steering pump for a hydroboost for power brakes. This will cut down the flow of the pump which must supply the hydroboost as well. Sorry I do not have anything that I can recommend for use with a hydrobooster.

What fitting is used to connect female hose end to this valve. I'm replacing my power steering pump on 1966 chevy c10. I can install old flow valve but not sure it will work with pump. Any way to connect traditional hoses to this. Thanks

That fitting will work BUT you must add a additional internal part that they also sell, order at the same time and save shipping! It does slow down the "feel" of the steering wheel. I would like to try a 1.5 gph.

if your hose has a o ring yes
July 18, 2011
John
This Flow Valve has 16mm O ring female and with our flare adapter number 91032921 will accept OEM style hoses with 5/8 x 18 inverted flare male hose ends. If your original hoses have a female end to match up to pump with male fitting out the back our flow valve will not be a direct replacement. In some GM applications the male fitting out the back will screw out of the pump similar to the fitting of the standard Saginaw style pump that is female. On our website there are thumb nail photos of the pumps at various angles and also a PDF instruction file to help with installation.

This part is specific to the GM Saginaw style pump and several aftermarket pumps and also the GM remote reservoir pumps. It reduces from the GM flow of 3 gallon per minute to the desired Ford flow of 2 gallon per minute. Ford had a few different styles of pumps used throughout the years adn doubtful this would thread into the Ford pumps. The gain would not be as great as acheived for the GM pump but could show some reduction in flow. Most Ford pumps are 2 gallon per minute as they come from the factory. What we may suggest to acheive your desired flow is our adjustable power steering valve number 91032923.

Power Steering Hose Kit for 1982-88 T-Bird Steering Rack to GM Pump
(Part #91032535)
                        

Our standard power steering hose assemblies are an inexpensive alternative to the more costly stainless steel braided hose kits. This set adapts a 1982-1988 T-Bird/Cougar rack or our 91034340-POW rack to a GM style pump. Return hose will normally need to be cut to length.

The pressure line in this kit has an inverted flare fitting at the pump end along with a 14mm O-ring fitting on the rack end. It also comes with an adaptor so that it can work with an O-ring style (metric) pump fitting. We suggest using power steering pumps 91032922-GM or 910-32908.

Kit includes:

  • Adapter for the GM pump, to allow it to work with both metric O-ring and standard inverted flare style threads on the power steering pump fitting.
  • The fittings that go into the 1982-1988 T-bird rack which are 14mm O-ring (high pressure) and 16mm O-ring (low pressure return) with the smaller O-ring fitting hose end being the pressure side for the rack.

Mustang II-GM Pump Power Steering Hose Kits
(Part #91032530)
                        

It is common to use an early GM power steering pump with a Mustang II power rack and pinion. Our Mustang II/GM pump power steering hose assemblies are an inexpensive alternative to the more costly stainless steel braided hose kits. The return hose included in this kit will normally need to be cut to length.

This has an adapter to allow it to work with both metric O-ring and standard inverted flare threads on the power steering pump fitting.

This will work with the 1974-78 Mustang II power rack and pinion in conjunction with the suggested power steering pumps 910-32922-FORD and 910-32908-BLK. When using an early GM pump with Mustang II rack, you will also need flow reducer valve 910-32918. This valve reduces the fluid flow from three gallons-per-minute to two gallons-per-minute, which cures problems of twitchy steering when these components are used together.
