I've been studying EFI fuel systems since I will soon be building one for the sports car project I'm working on. It seems that a lot of the folks that are running serious corner carvers and EFI are running a separate small surge tank. These have the EFI pump and plumbing. The surge tank is fed from the main tank by a low pressure feed pump in a constant return situation. The surge tank is always full so the EFI pump never loses suction in a corner. Sounds like a pretty good solution to fuel starvation, but a little complicated with 2 pumps and more plumbing.
