Was doing the n249 bypass on my auq today and have snapped one of the little manifold ports off when removing the pipe, it's going to the DV how do I go about sorting this before it gets dark.
I'm pretty sure they are pressed in, so drill out what's left, find a suitable size hose barb and drill and tap the hole to suit.
But temporarily you could chemical metal the hole over until you can fix it properly.
