I want to replace my old round metal gas tank in my Attex, mainly because it is a PIA to get in and out. And some of the bolts have vibrated loose and fell out of the mounting brackets. I also don't need a 10 gallon tank for my 16hp engine.

I'm thinking about a spun aluminum tank, 10x12 and will have an easy 4 gallon capacity?

Can anyone verify the diameter of the old round metal tanks?

Any other suggestions for replacement tanks?
