Hi guys, lately I have something loose under my truck that I randomely feel on the driver side floor. I was just under the truck prying and pounding on stuff and all I could find is when I hit the bottom of my fuel tank with my fist something inside bounce up and fall back on the bottom of the tank. Hope that make sense?

Anyways, what is inside the tank?

Thanks

fuel pump, filter, sending unit, float arm.

a common thumping under the feet of driver or passenger is lower front shock bolts too loose. they must be torqued to about 105 foot pounds.
