Inlet manifold PCV hose barb broke!

[glenhendry]

Edit:Subject should say barb, not bar.

This morning, when putting a hose clamp on this part (to find/fix a suspected vacuum leak (http://www.aulro.com/afvb/p38a-range-rover/153117-ems-thinks-lean-why.html)), the barb snapped off (making an awesome new leak). The plastic barb seemed very brittle, so be careful when working with it. I urgently need to replace this today as I have a full day trip tomorrow at an 4wd adventure park.

Does anyone know what the thread format and size is on the part still stuck in the manifold? If I cannot get the legit part today, perhaps I can get a bung for it. edit: this is the part (http://www.roverparts.com/Parts/ERR6880G.cfm). SCA dont understand the ERR6880 part number formats, Autobarn only have imperial fittings.

Thanks!

Im pretty certain it's a bsp thread, I replaced mine with a brass fitting from pirtek a few months ago. When removing it be careful of the stainless collet in the guts, mine went into the manifold, luckily I could simply open the throttle body and extract it.
