A severely burnt Dunedin man wants to thank those who helped him as his skin melted.
Shannon Taylor, 22, was in the back yard of a friend's house in Port Chalmers working underneath a Ford Falcon station wagon with the motor running.
He said he had incorrectly wired the fuel pump, which caused a spark, ignited fumes and created a "flame ball" at the rear of the car and he had caught fire.
"I rolled out and I ran up and down the path trying to put myself out."
The screams of his friend's girlfriend alerted two people to act and "save my life".
