Does anyone know why and what kind of build up that is on my fuel tank?
Thanks

I suspect it may be guck.

It looks like dust stuck in some sort of oil, but that pic is fuzzy so it is hard to tell.

Its the dark brown crap on the side of the tank
All im worried about iis it hurting anything??

I figured, is it inside or outside? What have you tried so far in removing it?

Ok I have little to no clue what it is my first try if it were mine would be a bottle of injector or fuel system cleaner.

The staining is farely new....all gas stations around me now are less then 10% ethanol...So it could be that..

You think it will hurt anything?

Any more suggestions?
I appreciate it

ethanol is bad for rubber seals and all that good stuff. thats why STC'ed airplanes dont use it

not a huge deal on the ski i wouldnt think.
