For anyone who is considering adding fuel injection, I'd suggest checking out MegaSquirt (http://www.bgsoflex.com/megasquirt.html) -- One of the things that many people have tried with it that works fairly well is using a small header tank in the engine compartment to pressurize the fuel rails which is filled with a low-pressure pump.
