Someone sells gas can vents on eBay, drill a half inch hole and install! Work great! No more glug, glug.
No need to go to flea-bay....
Stop in to any automotive parts store, even Wall World probably has them, and pick up a couple of standard tire valve stems....
Procedure
1. Drill 1/2 hole where the old air vents used to be
2. Remove the little valve from the valve stem
3. Pull the valve stem through the 1/2 hole you've just drilled until it seats
4. Remove the valve stem cap when pouring
5. Replace the valve stem cap after use
Which valves do you use, the milton ones I've tried disintegrate in gasoline.
So a while ago, the spout for my chainsaw gasoline can broke. I have been delaying replacing it, mostly out of fear of the new EPA versions. However, I went to cut firewood this weekend and spilled gas all over my 660 and finally decided to retire the old can, which was about 10 years old. I needed a few things at Home Depot, and picked up a can. I have always had trouble neating fueling up chainsaws, but this new can worked great, no mess. You simply turn a collar and push the spout. Anyone else agree?
