Hi folks! Sorry for jumping in on your thread. I'm not really much of poster, I'm just more of a lurker in the backround (reading through all your tech threads and keeping an eye on your for sale section 
) but this thread has caught my attention. I'm building an M3 trackcar and although I haven't tracked it yet (so I don't know if I'll be going quick enough to get fuel stavation issues) I'd like to do something that would help just incase.
I was having a think about all the options that people have listed and I'll apologise now if I'm stating the obvious. Feel free to correct me if I'm wrong.
Single Pump, Twin Pick up Option: Surely this would be no better if not worse than a single pump with a single pick up? I would imagine that as soon as one pick up starts sucking air the pump would loose prime completely and you'd be back to square one...This would be an issue on both left and right hand turns now.
Twin Pump, Twin Return Option: Seems to me like it could work well. You'd just need to sort the fuel pressure out. My only concern would be if you're low on fuel and cornering hard you might end up with one pump loosing prime more than the other and it would end up overheating and siezing up???
Single pump with return line relocated to the same side as the pump : Seems like the best option to me. Its also the cheapest. You'd just need to come up with a way to keep the fuel around the pumps pick up.
Kev.
