If it's leaking there, then the whole unit is broken.

As above,
the condition of the rubber bung in the end is irrelevant, one or both of the piston seals have failed.... & no they are not replaceable.

Just looked at a replacement, wow they are not cheap!!
There is an alternative to buying a new FAM7821 regulator....

I used this arrangement on my MPI with Metro 4 pot calipers up front & the rear brake pressure set slightly higher than standard -It suits my driving style & other people have driven my MPI & liked it (& i've never had a problem with brakes locking up).
