If you see the fuel tank, there will be little rust spots on them. The last picture, just above the orange cable thingy, you can see rust spots covered with black paint ?
That orange thing looks like a fuel line, but I'm interested in that pic. Can you link to another site with the full res pic for me? (I'm a spray painter). I'd like to have a closer look at that rusty bit. Looks to be some surface rust.
