Pat, one hose vents the vapour, the other returns oil to the sump, you need them both even for the pro-alloy tank.
I guess you could block tank and sump ends of that return and check the tank regularly, but the system works and never needs attention so makes sense to leave as is. Don't think anyone has mentioned plugging that return on here.

I've never seen one who doesn't use the return. 
Anyone else shed some light on this?

Graham i think there is a pipe that needs to be blocked off and that's what the metal bung is for in the picture at the top. But i didn't need to use it on my car so i don't know where its supposed to go.

I have a hard pipe kit so didn't get a bung, I assume that bung is actually to block the standard return in the 'boost/inlet to manifold' pipe rather than the return to sump. Never seen it before though so can't be sure
As far as I know the return to the sump is always retained. The PA breather (it's not a catch tank, it doesn't 'catch' anything) separates the vapour from the oil and vents it to atmosphere out the bottom of the car. The oil then runs down to the sump.
The bung is to block the rubber washing machine hose between the IC box mounted filter and the front turbo that the standard breather uses.
That's why oil is able to track up the front turbo pipe and into the boost hoses with the standard breather.

From posts It seems I have found 3 different ways of what guys have done with the return line.
1) Connect to the sump as stock tank and Pro Alloy tank is set up for.
2) Tank return hose goes to bottom of car/atmosphere instead of back to the sump and plug the sump.
3) Plug return hose coming from the tank and check every so often for build up and plug sump.
It also sounds like most that don't return back to the sump have a short stub of hose coming from the sump like Streetdragster just posted via another thread and it is plugged.
I don't hear of anyone having a direct threaded plug for the sump?

This is right!... its actually a crank case/rocker cover breather.The bung is to block the rubber washing machine hose between the IC box mounted filter and the front turbo that the standard breather uses.

If you don't have it connected to both rocker covers AND the sump you won't be venting the engine properly.
