What's in the Box
If you have a power steering pump using late model style O-ring sealed hoses that you need to adapt to traditional inverted flare hoses, this inverted flare adapter is a simple fix. Simply insert the adapter into the flow control fitting and then install your inverted flare hose.
Use to convert from 16mm o-ring to 5/8" inverted flare style.
- Use with Mustang II PS Flow Valve if using a GM Type I power steering pump (910-32908) in conjunction with a Mustang II power rack and pinion (910-34340-POW).

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.

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.
- 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.

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.
If you have power steering on your car and it has too much assist or a 'twitchy' feel to it you may have too much pressure to the rack or box.
This nifty valve allows you to adjust the pressure and get the road feel you want. It has a 1/4" npt inlet and outlet for the pressure line, and a 3/8" npt inlet and outlet for the return line.
Both pressure and return line need to be plumbed into this valve.

These steel fittings have a straight thread with o-ring on one side and the common AN6 on the other. Common to Ford rack and pinion and others.
