Plastic Gas Can Modification
« on: February 06, 2011, 05:56:06 AM »
If you dislike the new unvented or "self vented" gas cans, here is an idea from one of my hunting buddies.
Go to an auto parts store and get a short tire valve stem and remove the valve core. Carefully drill a 3/4" hole (with a hand drill, making no sparks!) where the vent should be (behind the top handle hole). Push a stiff wire from the new hole and out the fill/spout hole. Put the valve stem on the wire and secure with a bend in the wire. Pull the stem out and snap it into the 3/4" hole. Screw on the cap and you now have a vented gas can!  ;)
PS- BE AWARE OF GAS VAPORS, THIS PROCESS CAN BE DANGEROUS!!!! :o

another tip or two on your gas cans is, on some a 12 shell with the crimp cut off fits tightly over the nozzle and on some the cap off a bottle of HEET will snap right on.on some a 20 gauge shell will fit tightly enough inside the the nozzle to make a good plug.for some reason them pesky original lids seem to dissapear.

I forgot to add that it also shortens the time it takes to fill a mower tank, a fact my wife likes. :)

Went to auto parts store today and purchased a pack of valve stems.  Did't pay any attention to the package.  Got home and read that they were for a rim hole of .451.  I measured the part of the stem that seats in the hole and it was about 6/10 inch.  I think my stem will compress and seat into a half inch hole or maybe even 7/16ths.  Have no idea what drill bit would equate to .451.

Better measure your valve stem before drilling that 3/4 hole.  Might put a little KY on mine to ease it in.

Charles according to the drill bit chart I have 0.451 is 7/16 (0.4375 to 0.4528) if you Google drill bit conversion chart there's a lot of charts you can print off and laminate to hang in the shop hope this helps best of luck

Well I used a 1/2 bit and it is very snug.  Should work OK.  Now I have to get the stem out.  Don't have a tool for that. 

Thanks for the conversion info.

Charles, use a very small screwdriver to remove the stem/valve, put a bit of oil in there first. Don't worry about the threads, you won't be putting the valve back in.

I've used small tweezers to remove them before, seems like the tweezers from a Swiss Army knife might fit...

You can buy dust caps with the tool made onto it or find them on lots of old trailers and farm or other work equipment.  ear

If I ever modify another gas can, I will find a shorter valve stem than the automotive one I used.  Even a right angled stem might be good.

Overall, this is a very usefull modification and I thank the author for telling us about it.

Thanks for all the replies. I have a couple of the old style vented cans with the little flip open vent. One of the caps broke off, so I simply replaced it with a valve stem. Still waiting for the other one to break so I can have
ALL of my cans vented the same. ;)
