Unrelated to heating, gas cans

anyone have any tricks to keep the gas fumes from getting into the garage? Back in the old days, my grandfather had shotgun shells for this purpose, but no more around.

thanks for any tips

Coincidentally and unrelated, the last couple posts I’ve submitted, the first one did not stick so I repeat the process and the second time it sticks

    Get new cans

    You know the new style that leak gas when trying to fill something.

    Usually you take the spouts off and reverse them so they point into the tank and then they have a blank plastic cap to cover the spout hole.

    At least those have spouts which are long enough. A lot of the newer ones have short spouts and fancy valve arrangements which don't work anyway, or at least not for long.

    I take the spouts off and store them and use solid screw on caps. And no, I don't remember when or where I got the caps…

  • As much as the mechanisms are terrible on new spouts and drive me bananas, I think it's time to replace those. The right one especially as that plastic looks sun bleached which means its going to be brittle and much more prone to breakage. On the left one you might be lucky enough to find a cork or rubber plug that conveniently fits into the spout (confirm rubber types! not all like Gas)

    Those slip on caps will pop off if the can warms up. Almost instantly when you put them in the sun.

    Some of the new design RV gas cans are real

    if you do some googling yo can find solid caps to screw on in place of the spouts. you can get replacement vent caps too although i think that snap in style always leaks a little.

    you can get the ventless type can and an aftermarket plain spout and solid cap for it, those will keep the gas fresh longer then the ones with the vent with a snap cap.

    I stopped using those cans a few years ago. Me and most of the people I know switched to these no spill cans. Not one failure in more than five years.

    I’ve gone all electric, mower, string trimmer, blower, small chain saw, and pickup truck

    No more gas cans in the garage!

    i think some searching will find a cap for the screw on vent cap on the can on the right

    I'm sure glad I don't live in a world where there are no shotgun shells!

    The can on the left does not have a replacement spout that fits, so you can glue a cap on a short chunk of PVC to slide over the top or shave down a dowel/stick to fit inside. I have a 1 gallon can with a bolt wrapped in electrical tape plugging the spout that's been that way for 30 years. Maybe even an expandable rubber plug like is in a boat?

    The can on the right you can do the same or just go to any store that sells hardware or power sports type of stuff and get a replacement spout for like ten bucks.

    Or buy the new cans, immediately throw the spout away, and install a replacement. You have to drill a 1/2" hole in the back by the handle for a vent, but the spouts come with a barbed vent that you push into the hole. The cool part about these is they also make a big bore spout with about a 1" hole so you can empty it in about 30 seconds. I have several of these for diesel fuel as most diesel equipment has fuel fillers that are in a place where you don't want to hold up a 50 pound can for 4 minutes.

    Otherwise if you're into nostalgia, there are several hundred shotgun shells in my dumpster at home that I'd happily let you take your pick of.

    I use Safety 2 cans.

    They can still vent to relieve pressure but I've never had it happen.

    No, they're not cheap but they work and they work well.

    The valve setup makes filling even small things easy because you can throttle the flow and stop with your fingers.
