I actually found a post in a different area on the forum of someone with the same problem! They used super glue to reattach it.
I've come to the conclusion of actually using a higher temp silicone to reattach the elbow to the cover, then using a delete kit. Ends up cleaning the engine bay up a little bit overall as well! Still going to keep an eye out for another cover though just in case the silicone decides to out itself.
Here's the delete kit I decided to go with;

HOPEFULLY I WON'T BREAK ANYTHING WHILE INSTALLING IT.
WISH ME LUCK.
