A very good friend has accidently pumped 15 gallons of gas in his 4 door megacab 4x4 2500 auto. :{ He said that there was a quarter of a tank when he pumped 15 gallons of gas in it. He did not realize it was gas and drove off. He drove about 3 miles when it started to act funny, realized he pumped gas in it and shut it down. I hauled it home on my flatbed trailer but we had to start it to get it on. The truck did not start right away, but it did start. We unloaded it and parked it in the shop. What is the easiest way to empty the tank? I figured we would siphon all we could out of it, remove the fuel filter, turn the key on and let the pump drain the rest out of the tank. Add pure diesel back in the tank and turn the key on to pump it dry . I thought we would do this 2 to 3 times. Any thoughts ???
