remove the left hand fuel sender and siphon the fuel from the left hand side.
You can use a window washer pump if you don't fancy getting a mouth full of petrol.

Fuel only transfers from the LH tank to the RH tank when the fuel pump is running.
Either run the engine while you are draining the tank, or 'hotwire' the pump relay (30 to 87). Either way, don't run the pump dry.

I did that once, but since the bottom of the window washer pump has to be submerged in the fuel to work and visibility in the tank is at a premium not to mention the possibility of wires powering the pump being submerged I think I'll give it a miss next time and hot wire the fuel pump.
