NEVER us gasoline as a fuel, it is carosive to pvc and is TOO flamable, to put it simpley

well i was saying to use a metal tamk and you could theicken the gas with a light oil like 85-90% gas and 15 to 10 % oil.

once agan read these two boks

Personally i would never build one of these as my friend's father got third degree burnes when gasoline fumes went up his pants.... but if you are going to build one of these i would maybe suggest using a water type fire extiguisher instead of PVC as a tank. i would think that an aluminum tank is alot less likely to have flaws or other things that could cause a backflash than solvent welded pvc. it also wouldent be affected by gasoline. u can get water type fire extinguishers of ebay, built in valve, filled by schrader, gauge to 100 psi on them, exactly the same as a PVC chamber but way safer. also lighter probably.
Found a video, this looks like a gas filled extinguisher with a blowtorch held in front, works dang well though.
