Power Steering Hose Identification

My power steering pressure hose recently developed a leak in the rubber section right before the metal crimp. this is an aftermarket power steering setup installed by a prior owner. is there a way to identify the part number of the hose that was used? I’m sure this is a long shot, but I’ve included a couple pictures just in case.

Aside from that, is there a universal kit or some other option that you would recommend?

 

Those hoses are often the ones that came with the "donor" steering box, so the application was the original vehicle. Sorry, but I have no specific application. Mine was from a late '60s Chevelle.

What engine? It would be good to put mechanical/equipment specifics in your profile and/or signature file.

As Donny suggests, the hose likely has some connection to the engine or donor vehicle. If you have a Buick V6, I would start by looking at pictures on RockAuto. A Buick V6 or V8 might be the donor for a 225. I'd check maybe a '65 Buick Special with a 225? Also, these are commodity GM pumps used by a lot of manufactures like ... Jeep! CJs from 1972 on could come with power steering using a similar configuration, and a hose from that app may work, even if not identical to what you have.

J-trucks are similar but likely longer. More Information for EDELMANN 70992

Do you have a friendly local auto parts store (FLAPS) that you are a good customer of? Ask them to order in some candidate hoses that you can compare to yours.

You last option would be to find a local hydraulics shop and have them make a hose for you. These shops mostly service construction equipment hydraulics I presume, but they can make hoses for any app.

Also, there are two broad groups of steering gears; those with flare fittings and those with o-ring fittings. This looks like a flare nut; to get o-ring hoses, go later, like '81 CJ.

 

Then you have the additional challenge when someone (like me) uses the GM pump and Ford steering gear. Custom hoses should be available in any city but you often have to bring them the hose ends/fittings.

 

Thanks guys. It looks like the 60’s Chevelle hose suggested by Donny may be workable. I’ll see if I can get my hands on one to compare to my existing hose. From the images it looks like it makes a 90 degree bend at the pump side (which may actually route better than my existing hose which does a 180 bend)

I was able to ID my steering box. It’s a pre-1980 Saginaw 800. So it has flared fittings as timgr suspected.

 

I got the hose today and it’s really close to working. Only problem is that the bend on the steering box side is too low, so the hose doesn’t clear the frame. Rather than trying to find a hose with a deeper bend, I was thinking it may be easier to get a pre-made extension, if one exists.

Does anyone know if that exists? Basically need a straight tube about 3” long with 11/16” SAE inverted flare male on one end and 11/16” SAE inverted flare female on the other end.

 

You can buy flared tubing with a flare and nut on each end. I'd guess 6" would be the shortest available. This will be kinda long for your purposes, I think. You'll also need to buy a flare union; these are widely available for 3/16" tubing, but maybe not for 3/8" tubing.

 

Would adapters and AN fittings be a better option? Seems like adapters are readily available to go from 11/16 steering box and 5/8 steering pump to -6AN.

I would need the fitting at the pump to be a swivel elbow, but I can’t find anything confirming a fitting like that is appropriate for use in a high pressure situation. Can anyone confirm?

ive never worked with AN tuning, but it looks pretty straightforward with no special tools required to build your own custom length tubing. Thoughts?

 

JMO - I'd try a little harder to find a power steering hose that will work without adding extra fittings.

Exactly which part almost fits?

 

The side going to the back of the pump looks like it will be a perfect fit. The problem is the side going to the steering box. It’s also on the short side, so if I try to modify it in any way (like unbending the 90 degree angle to about a 45 degree angle) it will not be long enough to reach.

In order to clear the frame, the hose needs to rise up about 5 or 6” from the steering box as it curves back toward the motor. I did find a hose that is intended for a mid 70’s Jeep. The picture doesn’t look like it bends any better, but it is longer and does have more metal tubing on the steering box side, so I may be able to bend (or unbend) it a bit to make it fit. Image attached.

 

Here is an alternate way for the hose to be routed.







I had the local Napa store put a different fitting on for the pump end of this hose for a better fit.



A hydraulic shop may make a custom hose setup for you.

 

that looks like a really good option. Thanks.

 

Respectfully, I would ask my question again - which application almost fits?

 

Sorry I thought you were asking which side of the hose almost fits.

it’s a 1965 chevelle hose that almost fits. Gates part number 352300.

 

So I ended up getting a gates 364160 to work. It did require some unbending of the factory bends on the box side, other than that it worked great. So this may be an option for anyone that has a v6 with a pre-1980 Saginaw 800 steering box, and needs a power steering pressure hose with an 11/16 flare on the box side and a 5/8 flare on the pump side

I can’t for the life of me remember what vehicle the gates 364160 is intended for. I just went on rock auto and started randomly searching for pressure hoses for mid-70’s American cars. I picked it because it has a long metal portion on the box side of the hose, allowing me to make slight bends to route it correctly.
