Help! $400 hydraulic hose in Jeep (and I thought Audi was expensive)

[Zsolt]

Sorry for the WOBW, but am helping out my girlfriend to repair a leaking
   hose in her 90 Cherokee 4.0 L. The hose is going from the ABS pump to
the master cylinder, and it costs over $ 400 CAN. I am hoping to have
the hose made and I don't have to buy an OEM part. Could anyone tell me
what the pressure is in this hose? I am told the reason it's so pricey
is that it has extreme high pressure.

I would need to know this ASAP, so I can have it made (if possible).

Thanks,
   Zsolt
