Small dia ( ~6" dia )/Tall tank ( ~20" high) similar to sprintcar type should fit neatly in RF corner of passenger footwell & not bother pax feet too much. Poke top of tank out top of footwell to keep all but the lower feed to the pressure side of the pump in the engine bay will keep all the potential leaks out of the passenger compartment & all lines etc relatively short. Keeping engine at standard height allows a slightly deeper dry sump pan to help with crank clearance etc.
