Dan, I only have the 10g and 33g tanks. My 10g kicker is in the left rear, and has to be set to right for it to pull fuel from it. Just figured since mine has a under seat tank they didnt really put alot of thought into Left/Right on the switch. I will tell you, once I just reached down and turn it 90 deg before blast off, thinking I put it on the big tank. You wanna look like a fool? Floored it got on plane, engine shut off…. I turned the dial to the blank spot (off)
