has anyone tried this yet. ive seen this video once before but im suprised ive never heard ppl talk about it.

I don't even need to watch the video to see that it's a terrible fire hazard.

There's a lot of better ways to destroy your engine than this.

you do realize gas vapors are highly explosive right?

Yes I work in a chem/pharma plant I deal with flammables all da time. Uel lel vapor density bla bla. I've seen some videos of other ppls setups that r a lot safer than this. This video was just a basic way to show how the system works.
