Why is hinge at front of the filler neck? All standard tanks I have seen have the hinge at the rear. Custom tank?

Fibreglass tanks have the hinge at the front.

Under current legislation, these tanks are not allowed on road going bikes without proof of resistance to ethanol. This applies to the EU as well.

In Norway you are still able to buy 98 octane petrol without any ethanol. There was some public discussion last year about introducing ethanol into 98, but it was abandoned after a large public outcry from vintage vehicle and boat owners. Some petrol station chains have even pledged that they will continue to sell ethanol-free 98 even if it becomes allowed to add ethanol nationally.
I also did some quick searches and I could not find any information suggesting that fiberglass tanks are regulated in Norway.
Also, I have two fiberglass tanks: one roadster and one Dunstall. They are in great condition and I see no need to change them if I don't have to.
Edit: I noticed after I wrote the reply that you're from Norway as well, mdt-son. I found in Chapter 22, §22-1 second paragraph of Kjøretøyforskriften that the fuel system has to be suitable for the fuel you intend to use in it.
As long as there is no ethanol in the fuel I use, and considering that vintage bikes have been using fiberglass tanks for quite a while without problem with the correct fuel, I would consider the fuel system as suitable for the fuel I intend to use in it.
But I would consider changing the tanks if they pose a major risk or there is some regulation I am not aware of. But I see no need to do so unless I have to.

Please check ChatGPT for guidance on likelihood of approval of a polyester-based composite tank on a vintage motorcycle, fuel selection notwithstanding. You will find it unlikely our "DMV" will approve it, for several reasons. The question is about what the tank endures, not the petrol type you chose to use.

Finished hooking up the new wiring loom today. Every switch and connection worked on first try, except I had switched two wires when hooking up the main headlight bulb. I got a lot of great tips on how to build a loom from How to build your own wiring loom.

Nice job @solbero and a very good choice to use “Japanese” style 3.8mm bullet connectors. They are far superior to the Lucas bullets, which were ok back in the day, but designed for cars really, and being rubber covered impossible to spot corrosion and are an absolute bear to separate.
If you intend to future proof your fiberglass tank, I can thoroughly recommend Flowliner tank sealer. However, you may need to get somebody in the U.K. To post it to you, as they can’t post abroad apparently.
Thanks for the tip. I have looked at Caswell Tank Sealer (recommended in Norman White's book). They seem to be shipping abroad.
