You can run the Walbro fine with no other changes. I don't know what would happen if your fuel pump dies while you're driving. I wouldn't think it would create a lean condition because your car would basically just die if it stopped receiving fuel. If you're going to keep driving around on it until you get the Walbro, I would definitely stay out of boost though... if you're just crusing at 1.5k-2k rpms and fuel was cut I can't see there being any damage done to your engine.
