Hydroboost Hose Question

@CharlieLed

I have a GM Hydro boost running off a Saginaw P Series Pump.

My Question is can I just buy 3/8" High Pressure Hose and put 6 AN Swivel Seal Hose Ends on it or does it need to be made by a Hose Professional for proper seal?

Also if you know what are the Thread Sizes on the PS Pump Outlet and Hydro Boost Inlet?

Twist-on hoses will not stand the pressure, you must have the fittings crimped on.

That's why we ask questions. You wouldn't need to lube anything under the hood again this year. The mess would be impressive. I think Saginaw pumps are capable of pressures well over 1000PSI

Earls makes braided line with steel fittings for power steering/hydroboost applications.


I just finished plumbing up mine using a Ford hydroboost and pump. The Ford had metric sized fittings and were available lots of places.

@fatfenders For sure I do not want that mess ever! @Ken Newman Thanks for the recommendation I am checking with a Local Hose Shop Tuesday before I order Earls online.

That's cool. I would have used OEM hoses if they fit nice, but the master cylinder on my COE is up much higher than a regular pickup. My son has a hydroboost on his early Bronco and used braided hose. It works well.
Good luck,
Ken.

The Black Braided will match the Fuel lines I am using so that is my preference anyway.

I'm using black braided for my fuel lines also. I used the Jegs brand for that and I'm not real impressed with them. The Jegs brand fuel injection to -6 AN fittings sucked. I replaced those fittings with Earl's brand.

Another source is Fragola Performance Systems. They have a special section on power steering hoses.

I went to a Local Hydraulic Hose Company and here is what I ended up with. The Reusable 90 degree Fittings were $34 each and the Hose was $4.60 ln ft.
Does not seem like the Best Price but it solved the problem and I know the fitting works with their hose.

The Clerk says the fittings can hold up to about 3500 psi and the hose 2250 psi so I should have no problems.

Thanks, tightening down four fittings was a pretty good workout. Makes me more confident they will work great!

I agree. The tight fit of the outside nut, and the inside threaded fitting made me confident it would be a nice safe connection.
