Hey,
I've invented an alcohol based gel fuel that I need to vacuum in order to remove bubbles obtained during the mixing process. I'm a bit worried about vacuuming it due to the strong flammable fumes that would go through the pump.

Is it safe to vacuum and if it isn't, is there some sort of vapour filter I can attach between the chamber and the pump? I have the 26L Starter Vacuum Degassing System with the DVP EC.4 Compact Composites Vacuum Pump.

Thanks
