An empty tank would probably ignite if an ash from a lit cigar went into it but a full tank of gas might not do anything....

I WOULDNT WANNA TEST IT THOUGH!!

True, it's the vapours that blow. If I recall correctly the super at my old building, who worked on cars a lot, once said he lit a full tank and whoever was with him made a run for it.

Anyone who has seen the extended version of The Blues Brothers knows they left the nozzle unattended while gassing up and what happened as they left.

I saw a video in which a guy welded a tank breach. He gave the gas filler a couple of shots from a fire extinguisher before starting but apparently it wasn't quite enough. On the first strike of an arc a small flame started licking through the breach; the guy was unfazed though and resumed welding almost immediately.
