I have one of these and I noticed today that I didn’t close the lid properly the last time I used it. The top yellow stopper was on top of the black lid instead of under it to make the correct seal. It has been like that from Sept. until now. I need to use the gas for my snowblower soon but I am wondering if not having the correct seal for that long will effect the fuel inside and whether I should use it in my snow blower.
Thanks for anyone that can help
