This little incident happened when i was 16. I was working on this 1950 chevy stepvan, and i was trying to get the motor running so i had to rig up a fuel pump to the carb, and the fuel pump was pumping gas from a one gallon container. I didn't check to see if the spark plug wires were cracked...and they were, and i also didn't check the old fuel line running on top of the engine to the filter to see if it was leaking....and it was. can anyone guess what happens next........... when i go to start the engine it runs for a few seconds and turns into a fireball i was so worried about getting the fire put out i forgt to disconnect the fuel pump which kept feeding the fire. i got the fire put out with only a few burnt wires, and i was not injured in this little incident.
