Any harm in switching a plastic can that was used for gas to diesel ?
I use a yellow can for my diesel, but sometimes if there is a big project or snow storm on the horizon I like to have a second can of fuel. Rather than buy a second yellow can, I use a red can. I made up 3" x 6" luggage tags out of 3/8 plywood scraps. I have one that reads Diesel. The tags have a loop of cord and I hang them on the red fuel can handle so I always know what is inside. I do the same for my 2 stroke mix. When not in use, the tags hang on a nail above the fuel cans.
