HP hydraulic hose

[Kneale Brownson]

 From what I've read on the Quattro, 200q20v and V8 lists, Colin, very few 
folks have found successful non-OEM replacements for the high pressure 
hydraulic hoses on these cars.  There have been reports of getting local 
hose suppliers across the country to duplicate the low pressure hoses with 
no problems, and, as I say, a few owners have managed to find cheaper 
replacements.   Several have reported getting a working hose that makes 
strange noises.  Many have reported apparent successes that failed shortly 
thereafter or in a few months.  I wouldn't bother taking hoses around to 
local guys who make up hoses for big trucks or heavy equipment.  Those 
hoses often have much larger flow rates, even though the pressures are 
similar, and I think that makes a difference.  For the amount of difficulty 
involved, especially in replacing the hose from the pump to the steering 
rack, I've gone with OEM.   I own several tractors and other equipment 
using high-pressure hydraulic hoses, and have no qualms about having their 
replacement hoses made up locally.  I went around to my usual suppliers the 
first time I needed a hydraulic hose for an Audi, and found nobody could 
supply new endpieces, and that decided the issue for me.  Subsequently, as 
I've said, I've read on these lists that only a few places seem to be able 
to make the hoses up correctly, so I've concluded the most reliable 
approach for me is to buy OEM.  I'll just skip an evening's dining out to 
make up the difference if I need to.
