I have a keyless push-button remote start configuration and would like to pump out old gas from the tank using the electric fuel pump. How do I electrically do this? Thanks much in advance!

The easy way would be to pull the fuel pump relay out of the engine room relay box and jumper power from terminal 1 to 2, that will power the pump in the way you want. The attached should get you to them.

Hi Steve! Your procedure worked to the letter! I was able to drain my gas tank in a short period of time with the electric fuel pump. Thank you!

You are welcome. It's a process that gets used a lot, much easier to drop an empty tank over one with 100 pounds of flammable liquid in it.
