Is the bottom of your fuel tanks black? -- Mine have no trace of anything black at the bottom.

It could be gunk or something else leaching out from the walls or bottom of the tanks?.

Both tanks are completely coated on the inside with a black film, not just the bottom

I’ve ran that diesel-kleen through before a few times, the Killem seems to help

sounds like maybe its time to resort to having the tanks professionally cleaned? -- I am thinking that someone had to have seriously neglected that truck at some point in its life. - One thing to look for when purchasing a used vehicle might be how black the tanks are on the insides?

I don’t understand why CAT would give it the green light?

Local rad shop quoted me $900-ish to clean both tanks
