I have a flat bottom 50 alum gas tank if anyone wants it. I was gonna put it in my boat to replace the 80 gallon tank in it but saw it has a small corrosion pinhole that is about the size of a nickel(not the hole just the corrosion) and if water is put in it it will seep out over time, very fixable...I am just gonna go poly because its cheaper but if anyone wants it feel free to let me know and you can have it. If not its gonna be trashed.
Its about 9 in high, 18'wide or so and just under 4' long..but I can get the specifics for anyone who wants it. It was made by Florida Marine Group
