flashback arrestor

[timfost85]

When installing a fuel vapor/hydrocarbon cracking system using PCV vacuum, copper pipe and bubbler, should I also install a flashback arrestor? Also, what makes the best bubbler?

Thanks,

Tim

I have a fuel vaporizer (MPG) and I don't use a flashback arrester. I plan to convert to a bubbler, to test it out, and in the past with same set up I also didn't use an arrester then.

I realize that most people don't, but I'm concerned about the what-ifs. HHO uses water and only converts what is immediately used. Fuel vaporizers have gasoline with fuel vapors leading to it. The latter seems like an erupting volcano under the hood if the engine backfires.

Might a bubbler be a good option? Anyone with experience? I also wonder if the water in a bubbler would evaporate too quickly as the heated vapors agitate it. Or might additional humidity be beneficial and help MPG (a kind of quasi-water vaporizer)?
