An update on my experience with the little electric fuel pump that's been in use since last summer.
Thing continues to work GREAT - much better starting than with the stone age vacuum pump.
However - I think (not sure) the output pressure of the little pump is a bit too high for the little scooter carburetter and it's wimpy little needle valve. I'm noticing that if i have the ignition turned "on" but without starting the engine, fuel eventually gets pushed past the fuel bowl and into the carb. body.
I'll no doubt have to change out the needle valve, but to ensure against continuing issues I've picked up a cheap little pressure regulator (about $20) that is dial-adjustable from 1 psi to 5 psi. The thing is made for carburetted VW Bugs - so anyone wanting to find one that's how to track it down. I have it set to 2 psi.
Here is a pic of the thing installed:
