4 Stainless Braid Hose Kit for Bosch Hydro-Boost® Power Brake Booster

Please note in the comments at checkout what power steering pump and box or rack, and what booster you will be using. For example Type I or Type II GM pump, Stock Pump and Box for (year, make, model vehicle), or a Ford rack and pinion, etc.
The high pressure hose has the stainless braid weave on the outside, and a PTFE (teflon) inner hose, uses high pressure threaded hose ends, and is rated for aircraft use. The high pressure hose goes from your power steering pump to the Hydro-Boost and then from the Hydro-Boost to your steering unit.
There is about 1/10 of the pressure in the low pressure side of the power steering system. You only need a light duty rubber hose and hose clamps returning from your steering gear and from your Hydro-Boost back to the pump reservoir. This kit uses high pressure hose and fittings all around, which is overkill by a factor of 10 on the low pressure side, but it looks good and it will have all the hoses match.
