How do I drain the gas tank on my [DSM]?

Racers often want to drain their pump gas and replace it with race gas beforehand. According to Steve Wells, the easiest way to do this is:

• remove the fuel line from the back side of the fuel pressure regulator;
• connect a 5- 6' piece of fuel line to the regulator;
• put the other end in a gas can;
• connect the fuel pump test connector in the engine bay to +12V.

Steve credits Norm Schilling for this method. He has also connected a switch in the engine bay for turning the fuel pump

Never leave the car unattended while draining fuel.
