I bought these gas can vents from E-bay. $17 shipped. The supplier is here in the STATES. I have 22 gas cans (16 of them I found in the woods over a 20 year period) 
for fuel for emergencies like hurricanes and such. It would take for ever to empy out a 5 or 6 gallon gas can. These vents cut the time in half. They are very easy to install. Find a flat spot on the top of the fuel can. First drill a hole in the middle of the flat spot on the can using a 1/4 inch drill bit then finish off with a 1/2 inch bit. Then using a plastic/rubber hammer pound in the vent. https://www.ebay.com/itm/ORANDESIGNE-15PCS-Gas-Can-Vent-Cap-Replacement-Gas-Container-Breather-Part-Allow/183912905197?ssPageName=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649______________________________________________________________________
