Decided that the easiest way to replace the master cylinder in my 73 bug was to remove the gas tank first, and in order to do that I had to cut the fuel line underneath.
Assumed the gas tank was almost empty and I was wrong and by the time I put a pan underneath to catch the fuel there was a pretty good sized puddle underneath on the floor already.
Mopped that up, cracked open the bottom of the garage door to help get rid of the fumes and proceeded to replace the master cylinder, which took a decent amount of time due to complications and then I went downstairs to relax for a bit.
In a matter of just a few minutes I suddenly couldn't breathe, my lungs were gurgling with fluids in and out and I couldn't get any oxygen and I got scared so I called 911 and those wonderful folks brought me some oxygen and I'm doing OK now.
That was scary!
