Hi David,
My electric fuel pump picks up fuel from the bottom of the tank already, so no worries there. However, the return line after my regulator utilizes the old pick-up location, so I'd have to find a spot for that...
I like the idea of the capacitive sending unit, no moving parts to wear out.
There are a few other options I'm considering:

All three of the above are 'two-wire' solutions, so they're simply some sort of variable resistance to ground.
