In a car with a build like that, I would probably consider handling an external surge can configuration as well. I just feel that the laundry list in your post with the 3 pumps in a surge can would actually work fine pending some details... but that its out of place in the average Z street car project. Its a layout description that displays you are able to think-around problems and solve it yourself, which is
, I just think that by the time someone put that in a viable "kit" it would be equally or more expensive than the way I did it, and a bit more external race-car style clutter versus my efforts to contain it all within the fuel tank... which admittedly contributes to its own downsides of annoying installation and serviceability, a common attribute of street cars.
