In my Duster I ended up with a custom built fuel cell under the package tray. I got tired of needing to keep the tank 1/2 full so I had a fuel cell built that sat on the kickup section of the trunk. The fuel pump sat down inside a one gallon sump and that solved all of the delivery issues. I also installed internal baffles to keep the fuel from sloshing around when I took the corners a bit too hard. It all depends on how hard the car launches. My Duster would launch right at 1G on the street with street tires so fuel slosh was an issue. You just have to do what you have to do.
