    I can't see how it could be, but I know history is full of such statements that proved false...If it is only moderately dangerous....??

    If it were not for CARB regulations, I would not be doing this, but to avoid using the absolutely worthless gas cans now on the market and having one of my legacy cans finally give up the ghost after some 30 years....

    Is the rubber plug I put in the "vent" O.K. It's the black plug you can see in the bottom right quarter of the pix.

    The yellow plastic snap cap that is supposed to be there will not stay shut -- it was part of a $10 USD OTC CARB can modification kit I bought for a worthless CARB can. Tried to fix the included yellow snap cap with Seal-All, but it did not work.

    Considering I never open vent caps when filling saws and brush cutters anyway, I figure the rubber plug should be O.K., nothing falling in the can or anything. Supposed to get dangerous winter weather this week....maybe a half-inch of snow (but, seriously, they predict that much all the time and about 10 percent of the time it turns into1-3 FEET).

    Without comment on the vent safety aspects, the first question would be compatibility of the rubber material with gasoline.

    Not seeing how it could cause a problem with stoppering hole. It should blow out in pressure gets high. Most rubbers aren't cool with fuel though. Needs to be nitrile or viton.

    Was a bit worried about rubber/gasoline.

    Remember a high school boyfriend stepping in a puddle of Chevron and his shoe sole vaporized a bit, sending him flying.

    Gorsch, I do not want to spend more on this....what about a wad of aluminum? :eek::whistle:

    Powers that be say cork is sorta O.K., but binders used to make cork fuse together, not so much.

    Maybe I can cobble a bit of nitrile glove around the rubber stopper.

    My thick gloves are 8 mil and supposed to be extra resistant to chemicals...but just remembering I sometimes use super duty gloves for work. Poked around the web, I think they are 15 mil. I can buy a pair for around $4USD. BIG pain.

    If the new gas cans really worked, it would be one thing. But using them I spill a fair amount so I don't see where I am being environmentally responsible.

    I'm so grateful a raccoon who is really stupid, fat and overfed by even stupider humans chewed a hole in my old gas can in the forest next to my woodchipper a few years ago... The type of plastic gas cans they've been selling in recent years work so much better, never leak in the usual places spots and have no vent hole that needs to be plugged to prevent leaks because its integrated into the main outflow valve.

    Ah, and yet the can I am replacing is at least 30 years old and probably closer to 40 years.

    Pretty good lifespan. And I exaggerated a bit in that the only thing wrong with the old can is it migrated to my brother's house in Seattle last summer and who knows if I will ever see it again.

    About the 'rubber gloves', try a small test, say one finger pocket, away from the house.

    It may not be easy to find but a glass stopper is it is pretty well impervious to anything..

    Fuel lines are rubber, at worst, it will swell and block the hole even better.
    Another fix is a short piece of fuel hose that will just fit in the hole and a full thread screw and nut that just fits in the hose.
    Tighten the screw once it's through the hose until it just holds the nut, push in the hole and tighten the screw, that will pull the nut up inside the hose and plug the hole no problems .....

    I seem to recall a YouTube, to create a practical vent, guy drilled a hole on the back shoulder of the can, pushed in a tire valve, the innards removed, with valve cap in place.

    I'm for metal gas cans. They do not outgas as plastic allows VOC's to permeate through the walls.

    Yellow retro fit snap plastic plugs are available, should one want to vent the can for easy pouring.

    A smooth 1/2 inch hole is easily droll through either a metal or plastic can.

    The Yellow vent easily snaps in.

    If the stopper isn't regularly being pulled out, I'd just cut a finger or so off a disposable nitrile glove, and stuff the stopper into them.
    There are several types of 'rubber' used on the car, and likely none of it is natural rubber.

    Rubber Chemical Resistance, Rubber Chemical Compatibility, Page 3 - Mykin Inc

    The bolt and hose solution is more permanent than the glove finger and stopper. I'll just add a couple of washers will prevent the nut and bolt head from slipping into the hose.
    As long as the fuel doesn't touch the rubber, it should last a fair time. Fumes will eventually mean needing a new stem.

    I had a small, one gallon jug whose yellow snap on cap broke off and got lost. Used a wooden golf tee that I would shove down into the hole; easy to pull when pouring. Used it that way for decades. :eek:

    This video's pretty good:



    He provides an Amazon link for vent caps, in description Basically four mods:

    1. Remove child-lock tab from spout cap.
    2. Remove spring from spout
    3. Add vent
    4. Remove strainer basket inside can neck

    @cyberpriusII

    Allow me to make your day a bit better!!
    I absolutely HATE the new pour spouts and have had 3 of them break in the last 2 years.

    Replacement "old style" pour spouts are available at Tractor Supply for about 10 bucks.

    gas can pour spout at Tractor Supply Co.

    I live near Seattle... Let me know how to sneak in to his garage and get it back for you? You can't so easily give up on a 40 year old gas can!

    The can was my father's favorite. We KNOW dad had it in the mid-90s and probably in the mid '80s. Big Bro helped us drop and buck some large firs last Sept and the can ended up in his truck. Now it is guarded by brother's rott, Rocco. That dog only tolerates me and most dogs love me. I would say the odds are not in your favor.

    AT the moment we have six five-gallon cans, one gallon and a half can and one imitation gallon can. The 1.5 can is 92 octane non-ethanol saw gas. The rest are non-ethanol 92 gasoline. Power goes out here on a semi-regular basis in winter, although it is much better in the past few years. That's when the herd of Honda generators go to work,

    Cars are kept at half-tank or better from November through March. All Subarus, with Michelin X-Ice or CrossClimate 2 tires.

    And I need to go back to work.

    I got an elephant that can calm any guard dog down... Of course the neighbors might have doorbell cameras and the elephant hates drawing attention to itself. I'll have decline the heist, unless your brother lives in a rural area and not the city?
