so soon i will be dropping my gas tank and replacing the fuel filter while im at it.. my car hasnt moved in 2 years (by choice) so i feel like it could use some extra cleaning throughout. i cant see that the fuel lines would need to be cleaned/flushed out, but im just curious if anyone has and what you may have seen? how did you go about it? im sure its not something that will need to be done, but i just wanted to throw it our there just in case.. thanks
