A properly sealed DeLorean gas tank will NOT spill gas out of the bottom. I bet your fuel pump support boot and/or cover boot are dried out. When this happens, the fuel tank looses it's seal around the fuel pump, and gas spills out. All vendors have these parts. It may also be possible that when the fuel pump got drowned in gas, it caused it to temporarily quit working. When the gas dried out later in the day, it worked fine. That is where you should start looking, other possible spots would be the fuel tank sender's seal, or the rubber filler hose's seal. Good luck. Jim Reeve MNDMC - Minnesota DeLorean Club DMC6960
