No gasket, I don't use any sealer.  Do check that the surfaces are perfectly
flat, though.  Sometimes even new components aren't.

I think 12 ftlbs is a reasonable torque value; but I don't have a factory
spec.

Also double-check how the rotor is secured to the shaft.  There should be a
pin visible; but some aftermarket pumps have the rotor pressed onto a
knurled shaft.  The knurls have been known to fail in service and create a
mess (in addition to the sudden loss of oil pressure).
