Sure, it's possible. I'm using a Facet solid-state pump back by the fuel tank (big filter of your choice goes between the tank and pump), and a Holley fuel pressure regulator in the engine compartment. The fuel pump is wired from the ignition circuit through a relay and an in-line fuse.

Fuel-injected B20s have a block-off plate that covers the hole where the mechanical fuel pump ain't. Find one of those. Note that you do NOT want the electric fuel pump from one of those cars -- it puts out way too much pressure (around 50-60 psi). The Facet pump puts out 10 psi, and you want to regulate that in the 2-4 psi range for your Weber.

Also note that the mechanical fuel pump you now have can pump more fuel than a DGAV can flow... if the engine is built out at all beyond stock, the downdraft carb is limiting your power.
