When it arrived it had such a tiny bore I was concerned that it wouldn't flow as much as the rubber return hose so I never tried to use it. Knowing nothing about injection I didn't know if there is much flow or just a trickle.

Two little bumps that feel a little bit loose. Tried squeezing them together and pulling at the pipe but no go. Tried twisting like a bayonet fitting but no go. Trying some Googling but no luck yet. I'm confident that if I'm to heavy handed and break the fittings its game over for weeks until I can get replacements sent from UK.

OK, sounds right. The injectors are fed with more fuel than they actually need and pass on the excess to the tank. A valve in the injector controls the point when the bypass begins. So a faulty injector/valve could cause the malfunction you describe. A spare injector (of the right type) would be dead handy for troubleshooting. Your second idea about sucking up air from an empty tank is unlikely. I always go for a full top-up when I get just below the quarter tank. I can't see any leaks between the tank and the filter housing.
As regards getting at the tee piece at the back of the rocker cover your idea might be worth a try. How do the connectors at the fuel filter top actually disconnect, and the connections to the tee piece?

Are the leak off pipes sealing?
old ones tend to become brittle and no provide a decent seal.
Air could be caused by that and it's an easy diagnosis/fix.
