Venting fuel cans
You will need a 19/32 HSS or harder (Cobalt is great but expensive) drill bit for the hole. When drilling a metal can keep the bit oiled & don't use too much pressure so as not too dent the can. After the hole is made, pass some fishing line or leader through the hole & pull it up through the filling & pouring hole, thread it through the tire valve & tie it, then pull the valve back through to the drilled vent hole & snap it into place. Voila!! It is nice & neat & works like a charm! As explained in post #22, you can lay a bead of silicone sealant around the rim if you like, but it is not really necessary.
Awesome. I didn't see it cause tapatalk didn't publish it. I have a tire shop just a couple blocks away. I'll get some tomorrow.
I discovered yesterday why the old cans work and the new ones don't. The old cans have a breathing straw in the opening collar installed before the bottom of the can is sealed up.
View attachment 275986 that is the aperture
View attachment 275987 and there is the straw going back to the dead space as the can is tilted forward.
The things these new computer crippled engineers NEVER knew because they weren't taught by Experiance.
