depends on the pressure differential between the fuel rail and combustion chamber.

That sucks.

I was thinking about the bucket under the drivers rear seat, what exactly does the bucket do? Can it be modified to add another pump in series instead of trying to stick 2 pumps in the one bucket? If that is a return fuel line bucket then i can see why it wouldn't be an option.

Is this the one that was almost done a while ago? Remember some rumblings about one near complete as we were looking into fabricating one...

Agree though, after some preliminary investigation myself one of the other options (or even simpler an inline version) is probably the way to go due to cost and the even higher problematic HPFP capacity issues.
