How To Make A High-Pressure Power Steering Hose At Home!

Unlike fuel and AC lines, power steering hoses are much more difficult to make at home without very expensive hydraulic crimping equipment. You cna always make a wire template and have a hose made at a local hydraulic shop, but where's the fun in that? Not to mention the hose will be ugly basic black hose. When we originally installed the hydroboost on our 1971 Buick GS back in 2007, we used the supplied stainless steel braided hoses that came with the kit. We have since replaced two of them with some custom hoses when we converted to rack and pinion steering, but kept the original braided line. Well, it finally blew apart on us, blasting the entire car with hot power steering fluid (the top was down too!), time for a change.
We are big fans of Earl's Plumbing, and we keep a decent amount of it on hand for projects like this. We used a about 4 feet of ‪@HolleyPerformance‬ Earl's Power Steering hose and two Earl's 45-degree power steering hose fittings that are designed to be assembled at home. The fitting collars thread onto the hose and then the fitting itself threads into the collar, making a leak-free high-pressure hose in just a few minutes. We have had two lines made with this same stuff on the car for over 10 years with no issues, but all of the stainless lines with compression fittings failed (at the factory crimps, not the compression joints), so we won't ever be using that junk again.

Thanks for your reply, it's good to see someone helping out,it's too expensive for a mechanic sometimes.

Good work from France 🇫🇷. to avoid losing pressure, respect the internal diameter of the pipe.

[@dylandesmond]

You don't have to push really hard, back it off 1/8-1/4 of a turn when you 1st thread in the hose... it'll still compress how it should and will actually lock in with more steel threads if you were unable to do it all the way up.

Not a fan of the hoses I would try to bend and make hard lines with an fittings on the ends and use as little of the hose at the end of the hard lines as possible at least for the pressure side that goes to power steering pump and I would run a solid hardline on the return line that runs from the steering box to the hydroboost side but keep as much hardline as possible and route them as evenly as possible towards the steering box or brake side for a hydroboost set up this is what I'm planning for on my build im just here getting ideas feel like the hoses look a little on the clumsy side would rather go for a cleaner look in my opinion but I definitely like the banjo fittings at the hydroboost end

@chevecrazy454ss hard lines are nice, but they dont give you much room for error or changes. This car sees a lot parts swaps as I use it for a test mule a lot.

[@AlexNeal-b6g]

Do you have a part number on the hose?...ive got a box of braided lines just wana make sure i use the rite type for my ps system.

I have a Mercedes and the high pressure hose for my car is on endless back order. Will this work on a Benz? I have heard that the high pressure line has a plastic bag liner on the inside.

[@Reddirtrodz]

Yes, you can make your own hose!

[@Dnasty1]

@@Reddirtrodzthanks how can I go about finding hose like this with plastic liner inside? Or is that not necessary? I believe the plastic liner is what is causing it to fail but it lasted 140k miles.

[@Reddirtrodz]

@Dnasty1 I don't know enough about the Mercedes to say, but I am not aware of any issue with using a standard high pressure hose.

Why don’t you like compression fittings? They are quick and very reliable. Probably as equal as what you’re doing. No specialty tools know nothing I use power. Steering compression fittings. And it’s been running for more than five years.

[@Reddirtrodz]

Because they are difficult to assemble and they fail spectacularly like this one did. I prefer high-pressure fittings like the ones I used here or crimped fittings.
It's a personal choice

[@buddyrebel_Garcia]

@@Reddirtrodz the ones I use are high pressure compression fittings like I said, I’ve been using it on my car for five years and I have had no issues. No leaks nothing.

[@Reddirtrodz]

@buddyrebel_Garcia this was a high-pressure braided stainless line that was factory assembled. The fitting itself broke. I hate compression fittings to be honest, they work but they suck to put together.

[@buddyrebel_Garcia]

@@Reddirtrodz really? I thought it was piece of cake. All I did was clean the tubing. I didn’t have to flare anything I deburred the inner. Then put the compression line and then I tighten up really good. I crushed the little thing that comes in. It was very solid. I did the same on top and to be honest with you. It’s been running for five years and no issues at all. let me give you the part number so you know what I’m talking about. I bought it at Napa auto parts. It’s like a power steering hose repair kit and the part number is PN.# PS 1000. From Napa. That’s what I used.

[@buddyrebel_Garcia]

@@Reddirtrodz Napa part number :

Can't see a thing what he is doing, should have close up guidance

Fair enough. We have been working on that with our videographer. We use multiple cams now

Sorry, rough day at the studio I guess.
