Interesting point. I also watch as many youtube videos before purchasing, but in this case how many scenery reviewers actually perform a fuel stop?
When the OP raised this issue on the Orbx forum it was not an issue I’d ever considered so I tested it and a number of airports. The ones reported are not the only ones with this issue.
When the FI Spitfire came out I made a few flights around Dover and took off from EGTB as I had just purchased that as well. Getting low on fuel I refuelled at Lydd EGMD. Later I purchased Lydd after watching a video, but as a test after the OPs original post I looked for a refuelling station there, and there isn’t one anymore. And that was from a developer not associated with Orbx.
Even Asobo’s EGCB Barton, has fuel pumps modelled but they don’t work.
