Hi All,

I am in need of the fitting where the power steering pressure hose attaches to the pump. There are two types of hose ends. One has a flare fitting, the other uses a straight fitting with an o-ring. I need the flare type fitting. I'll buy the whole pump if necessary. I don't care what condition the pump is in, I just need the fitting. Please let me know what you have.

Thanks, CobraRGuy

The only thing you should need is a replacement line which includes the fittings (on both ends). RockAuto, they're cheap. Just make sure you set the teflon o-ring in boiling water before you install it onto the fitting that goes into the pump's pressure port. Use a pick or screwdriver to fish it out of the hot water. Use thread sealant on the pressure port threads and clean them beforehand.

Thanks for your reply. Unfortunately the fitting I need is part of the pump. Yes, the hose has fittings on both ends, but the hose fitting threads into the pump fitting which has two o-rings on it and accepts the flare end of the hose.

If you look at a picture of any remanufactured pump you'll see the fitting in the pump. I just don't want to have to buy an entire new pump. There's a spring behind this fitting that comes out if you remove the fitting from the pump.

Is this a 5.0? Because the pump in the 96-98 cars was a little different.

This is the 5.0 fitting. I actually think this came on a number of Ford pumps from 1990-1995ish. I have a 1990 Ford escort pump on my fox and it uses this same fitting.

Thanks! I'm sure you're right about the '96+ cars being different. Yes that looks like it alright. It sure would be nice if it came with o-rings. That can be dealt with though. Much appreciated.

I might be able to measure the O-rings as I have a spare pump in my parts bin with O-rings. The spring holds the pressure relief valve in, which is deeper in the pump.

Oh, ok. New one on me. I'm a mod motor guy so I'm out of my lane. Unless it's a pressure relief valve we're looking at but I kinda don't think that's what it is.

The fitting itself is not the pressure relief. That particular pump used on the Fox and 94-95 Mustangs is referred to as a CII pump. That fitting goes on the outside, with a spring under it. Further into the pump under the spring is the pressure relief valve (i listed an example below). The fitting is just a fitting meant to lock the pump housing in place and adapt to the power steering hose (the one with the teflon seal). That's what I linked above.

This is the pressure relief which is further in the pump and unrelated to your question.


The C2 pump was used through the 80's and even up to early 2000's on F250's. Was used on the V6 Mustang up to 2004.

here’s what I meant to avoid confusion. Deep down under the spring is the pressure relief.

Dug out my spare fitting. This is an 87-89 fitting but o-rings seem to be the same. I’ll get a measurement at work tomorrow as I have an o-ring measuring tool. I’d recommend grabbing the fitting from NPD as ford discontinued the part so stock will dry up at some point. I picked one up myself for the spare parts box.

Thanks for checking the o-ring size for me, I appreciate that. The fitting is on it's way.

Are you using one of the upgraded pressure relief valves you showed? If so what difference did you notice?

I did, but I’m using hydroboost with upgraded lines to handle the increase in pressure. It makes the steering a tad lighter.

I would stick with what you have. I may actually swap back next time I’m poking around on my car. I think it’s more appropriate for trucks running wider tires

Why do you need a spare one? Looks to me like only the o-rings could fail due to aging.

Long story short, been playing musical power steering pumps. Never know when i'll need a fitting for some reason due to a pump not having one. I bought that fitting a while ago. I think i'm all set though now, aside from swapping out the aftermarket pressure relief at some point.

Small O-ring is a -113 O-ring.


The larger one is a specialized tapered O-ring. A -116 O-ring looks like it could be substituted.

Here's the fitting with the new O-rings installed. The tapered O-ring is on the table and what was originally on it. I have the -116 O-ring installed and think it would work.

This is an 87-89 fitting which is why it looks a little different than the 90+ fitting.

Thanks for this. I've never heard of a "tapered" o-ring. Could it be that a round cross section is now tapered just due to being against an angled surface for many years? That's what I would suspect.
