43 Gallon 5052 Alum. Fuel Tank - Is it clean or dirty alum?

Hey guys. I'm new here, & to scraping in general. My work in the oil & gas industry is slow (GD Obama), so I need the most for my scrap. I appreciate the discussions I have read here & would like some input from y'all.

I have a 43 Gallon 5052 Aluminium Alloy (up to 3.0% Mag, Chromium, & Iron) Fuel Tank (75"long x 18" wide x 7" high) I pulled from my boat. I was hoping to sell it as is, but it has 2 1/8" diameter holes on the sides & apparently some microscopic holes along one edge.

I looked at the ISRI Specs sheet & couldn't find a clear answer. When I scrap it how should it be graded? In other words, will I be able to get Clean Aluminium Price (like cans), Dirty Aluminium (like small engine blocks), or something in between? Also, will size be a factor?

Thanks in advance.

Unless it has non aluminum brackets , Bolts or other fasteners >> My yard would take as clean

Basically what scrap yards call "dirty" metal is something that has other metal attached to it. If your tank has any iron, steel, copper, brass, etc attached to it, then it is "dirty". If it has nothing but aluminum (no other metals), it is clean aluminum. Pretty much it in a nutshell.
