Looking for some info regarding pressure testing the flexible oil hoses on a CJ6

What pressure would these require testing at in PSI?

Any tips and procedure you may have would I'd be interested to hear details.

We make new hoses for our customers, with our partner, Aerometal in Hungary,
and I assume the Russians use very similar operating pressures as the
Chinese. However we test new hoses at 100 bar (1500 PSI) - dramatically more
than the pressure in service, but we feel that is prudent.

I would have to agree with Richard, any hose assemblies or valves which we make or overhaul "in house" are tested to at least 1000 psi.  That said, I would not recommend such a test to determine the airworthiness of old hoses.
