Gregg,
The tank in the 540 is 200mm deep and fits the BA/BF pump. The tank in my Harrison is 210mm deep and uses a VZ Commodore Ute pump(the pump from the sedans are longer), although I had to shorten the sprung loaded locoating tubes a bit to fit.
If you use a Falcon pump and require a fuel sender the ute pump has the sender attached to the pump, the sedan pump is just the pump as it uses a remote sender. The Holden pump has the sender attached.

Paul,
The VZ ute pump looks completly different to the crewman pump. From the picture of the pump in your gallery it looks as though the
flange around the top of both pumps are the same. The fabricator of the tank come up with a good idea in the way he held the pump down without using the O ring and circlip.
