No Fuel Leak No Boooooom

I do the exact same thing, change the spout and add a vent!

These modern "Straya" ones have small back side vents, that you unscrew to let air in as you pour, OR they have spouts on the inside of the cap, that you pull out and reverse, and the spouts have a big fuel out tube and a small air going back in tube, inside them.

@Life_N_Times_of_Shane_T_Hanson: We don't have any such gas cans here in the U.S. All you can find in ANY store are the plastic "Safe for Idiots" gas can.

@InfiniteMushroom: "Gloop! -- Gloop! -- Gloop!" = Good Times!. https://ezpourspout.com/ and https://4wheelonline.com/jeep/....images/products/roto

These plastic containers keep stretching under normal internal "gas pressure" - until they split - and a pin hole forms and they dump half the fuel inside them... They are unsafe.

@Life_N_Times_of_Shane_T_Hanson: Hell yeah! I found a hardware store near me that sells those kits.
