A 50 psi rubber line is probably intended for a carburated car.
Reinfocred rubber line should be well over 100 psi, and I've even
used some stuff rated at 300 or 400 (I think it was for some sort of
automatic tranny application) but that stuff is pricy. Oh
yeah...don't all the high pressure rubber lines on Audis have steel
braid over them?
