So after I posted this I took some time to read up on fuel systems and their quirks, learned that there would be several problems with using an air pressurized fuel system.

1) Vapor lock, the solution that current systems often use is a fuel return line, something that would be very difficult with an air pressurized system.

2) Safety concerns (I think this one could probably be dealt with pretty easily though)

3) Fuel tank integrity, never thought of that until someone posted it up above. This is the main issue that I dont think would make this idea of mine feasible =(

I do think that energy wise the concept would definately be way ahead of fuel pump, but the problems that arise with this system clearly outweigh any modest gains I would get.

Still, Would love to see it done lol
