I've noticed it on some jet engines especially the A330/340, I don't think it's for fuel dumping since the fuel jettisons are located on the wings.

What you see on the out side is a single drain mast but under the cowling there is a gang of drains going to a single point. If a leak develops on a engine accessory they dump over board rather than into the hot engine area. they are called case drains and hook up to fuel pump, hydraulic pump, fuel control, breather, burner can drain etc.

Fuel Leaks, Oil Leaks, Condensation, Hydro Leaks, basically anything that drips.

Taking a guess-- Them engines are quite hot,and as they cool after they are shut off, , moisture in the air is likely to condense.
I will bet they are for condensation to drain out of the engine housing.
Just a guess.

For any fuel that happens to leak. We have them on our C130s as well. They seem to always drip a tad.
