The pressure accumulator is used for hot starts as well as cold starts ... I
would recommend that you replace the thing.  I really doubt the
specification of the PA is that accumulator ... try to find the proper one
from a wrecking yard if at all possible ... but if you can find one that
fits in the same area and is roughly the same volume (and has proper
fittings I suppose) then go ahead and use it.

... BTW, you can find out what the nominal system pressure is from Bentley
