Dear Bob,
Very interesting work.

Re lighting your fuel unloading point - I think they would be more likely to use lamps on columns a little distance away. This would be to have the lights outside the area of a potential vapour leak so they don't have to use expensive vapour-resistant fittings. I recall a small fuel point at Cricklewood I used to pass each day which was lit this way but did have extra low-level bulkhead fittings to illuminate the hose connection points.
Regards,
John Webb

Dear Bob,
Re sheltering from the rain - the most important consideration in full-scale practice is to minimise water getting into the fuel. From photos in a couple of books, very small fuel points didn't seem to worry, larger points had an awning high enough to cover part of the side of the loco. In this case the lighting was enclosed fluorescent fittings hung under the awning.
Regards,
John Webb
