I have tiny rust spots all over my fuel rails. I have tried fine sanding, and something else that I cant remember. Any of guys had luck using anything else?
Take some Mothers metal polish, and fine steel wool...give it a rub down and that should cure it....its stainless steel, so hopefully its not pitted....i give mine a douche in that stuff everytime i can get at it....
The three fuel rails I've worked on have been chromed steel. You can use Lime-away it will chemically remove the rust and not leave scratches in the chrome. I then take spray rust converter and wet a q-tip and treat the rust spots so they don't rust again.
