I like Jerry Cans. These are very affordable.
You can easily spend $100 a can for higher quality cans but I think these are better than most plastic cans. I do have some plastic cans because I was able to get them for free. Over time I plan to phase them out but they hold gas. I have also bought old metal jerry cans I've found in thrift stores, yard sales, and antique stores but you have to make sure they don't have rust. I would say buy one and try it out. How do you like it?
Good question. I'm always learning but be careful that you don't over think it. It can be easy to not do something because you are still figuring out how to do it perfectly.
One of these fuel siphons is also good to have. I can't find the one i have but it looks like this one.
