Portable fuel tanks

[bigeasy1]

Not sure if this is the right forum, but have a question.
I'm looking for a good quality 6 gallon portable gas tank for the old (1989) Johnson 20 hp outboard on my small aluminum boat.
There are plenty available but almost all of them have lousy reviews.If only they still made the good old metal tanks of years past.Thanks a lot EPA!
Dont have the space to use a below deck tank, and dont need or want more than six gallon capacity.

Anyone able to recommend a particular brand or have an old metal one in good shape you'd like to sell?
