Could be a bad fill up then? I've been running Ethanol in our 2010 GT500 which uses the same hose and filter. Other than swapping out the first element shortly after we made the conversion the filters elements after that never looked like that.

I don't know, maybe. Ill give it another month of use and ill pull it out and see how it looks. Ill inspect the inside of the lines tomorrow and see if there is any residue.
