I no longer have them on my photo account. I no longer have the copies on my computer. Sorry. If I remember correctly they were just a diagram of how the fuel system uses the extra fuel overflow from the FPR to create a siphon to pull fuel from the passenger side back to the driver side. Works great until there is little overflow (read as WOT) or high speed long duration left hand corners. Which I did a lot of. Alternative was to put a second fuel pump you can turn on manually or with a wet switch to pump fuel back to the driver side. The passenger side had a drop in bucket just like the driver side did that you could buy a second fuel pump assembly and just drop it right in, as far as I remember. I no longer own an Rx8 thou. So don't quote me on that. You will have to investigate it yourself. Hope that helps. Cheers!
