Funny you had the same experience with a jackstand and a gas tank.
Years ago I was putting rear discs on my Scirocco and had the car up on sheetmetal jackstands.
You guessed it-- they collapsed, with me being crushed between a wall in the garage and the falling car. The fall caused one of the stands to scrape off a gas line and the gas line started leaking like crazy.
I must have made enough noise because my wife came running into the garage, only to see me being pinned against the wall. We pushed the car off me, and after the gas leak was stopped, she said "You will never get under a car with jack stands again, right?". Dazed, I agreed.
That was when I was officially authorized to get a lift.
Since then, I haven't used them, in any form, and I really enjoy the lift.
Maybe the whole bad experience worked out: I wasn't killed, and I got Official Permission to have a lift!
