Mustang Power Steering Pumps - Eaton Pump vs. Ford Pump

The Eaton Power Steering Pump on a Mustang has a separate pump and reservoir configuration.  Please note that  originally the reservoir was painted Argent (silver).

We receive a lot of email with good questions about all kinds of Mustang stuff.  A customer recently was asking how to tell the difference between the Eaton Power Steering Pump and the Ford Power Steering Pump on Mustangs.  I thought this would make a great little Blog post.

The Eaton Power Steering Pumps were used on the 1964 1/2 and early production 1965 Mustangs.  Ford then switched over to what is known as the "Ford" Power Steering Pump.  We are not going to be concerned in this post about Concours detailing or anything like that.  We are just focusing here on how to tell the difference between the two pumps.

The Eaton Power Steering Pump on a Mustang with factory air conditioning had a remote mounted reservoir.

We will mention that the Eaton Power Steering Pump would have originally had a Argent (silver) reservoir, rather than black like the one shown in our picture.  There is also an image here of the Eaton Pump on a factory air conditioning equipped Mustang.  You will note the remote reservoir on the pump.

Here is a picture of a 1965-66 Mustang Ford power steering pump. This particular one has the slanted neck to clear the air conditioning compressor on a factory air conditioning equipped Mustang.

The Ford Pump is also pictured.  This particular one, as noted in the caption, is one with the tilted or slanted neck to clear the air conditioning compressor.  It also should be noted that starting in 1967, the filler neck is smaller in diameter and used a different filler cap.
