so i had this weird metal rattle type noise when going over bumps. we checked the whole suspension at my work. everything was super tight, gave the fuel tank a tap and made the noise it sounds like something on top of the tank let go. maybe a bracket or something. the car drives 100% ok. one of my techs said his brother had an issue similar something about a prefilter bracket letting go on top of the tank. anyone else have a similar issue ever or heard of this. first time ive heard about this being an issue.
