These photos were kindly supplied by Brad of Whangarei and show Air Zealand’s Airbus A320’s, which are used domestically and internationally. Note the relatively untarnished metal surrounding the pipes, suggesting that it is a retrofit and it appears that rivets have been removed in order to install these. Also, note that these pipes are not evident in the image of the A320 taken from the Air New Zealand website at the time of writing.
Also, note that in the last two images shown of an aircraft in flight, which are taken from a YouTube video titled: ‘NOZZLE TRAILS – block the sun – focus on airports/aircraft’, three trails appear to be being emitted adjacent the left engine, although it is not known what model of aircraft this is, nor which airline the plane belongs to.

Close up of retrofitted pipes. See the photo below which shows where the pipes are relative to the engine.

Image taken from Air New Zealand website. The pipes shown in the first photo are not apparent.

Hi Clare, been a while!
That’s a pylon drain, you’ll find them on every A320 in the world.
Here is a link to a technical manual that gives a nice illustration. Page 141.

Brad forwarded the following reply to Anonymousatco, (who is a known disinformation agent to this site):
Writes Brad: “Firstly, the statement that Anonymousatco made that all Airbus A320s are fitted with multiple nozzles on each engine pylon is not correct. A simple Google image search of Airbus A320 engines reveals that there are a number of different pylon and engine configurations – some with nozzles fitted, as shown in my photographs, others with nozzles in different places and others with NONE AT ALL. The Lufthansa Technical Training manual states on p132, not on p141, that any leakage from fuel lines running through the pylon is drained overboard through separate lines in the rear of the pylon. Why would it be designed to drain a highly flammable hydraulic fluid, engine oil and possibly fuel into a super-heated jet exhaust? The question remains, why are these pipes being installed on both Boeing and Airbus, on both old and new aircraft, and on aircraft used by airlines that appear to be involved in spraying aerosol trails/ geoengineering?”
“Google image search of Airbus A320 engines reveals that there are a number of different pylon and engine configurations – some with nozzles fitted, as shown in my photographs, others with nozzles in different places and others with NONE AT ALL.” Could you please show me some of these, I would love to see them!
The drain is there to prevent volatile liquids pooling in the aircraft structure, that’s where its most dangerous. The exhaust behind the aircraft isn’t really that hot, and due to mixing with bypass and ambient airflow it cools very very rapidly, Hence the formation of contrails.
Brad replied: Look, they are there.
If you believe you are looking at contrails, how do you explain these images? For instance, that shown first in this video with large volumes of aerosol material from 3 areas, not 4 and this is a plane with 4 engines: https://www.youtube.com/watch?v=aQk9B7kjKrM
Also, how do you explain the 3 trails – which equates to 3 nozzles, in this image of a plane spraying aerosols? https://i1.wp.com/chemtrailsnorthnz.files.wordpress.com/2018/04/three-trails-2-e1525158882359.jpg?ssl=1&w=450
