A "highway" tag in OSM is supposed to have one of these values: https://taginfo.openstreetmap.org/keys/highway#values .  None of those are hashtags.
Things processing OSM data tend to do spatial searches, so it'll be obvious to them that this fuel pump is within https://www.openstreetmap.org/way/118521382 ("Junction 14 Mayfield") that you added with the website https://junction14mayfield.ie/ - so they'll already know where it is.
