[Bobcat]

Kramer .... I had the same experience on mine , and called Bob P. about it . He said that there were doors/flaps in the tank to keep the fuel where it was supposed to be and that was what I was hearing when the car was moved ( gas was sloshing around in the tank ) . Also , when the engine is running , you`ll never hear them !
I was a little paronid about it as I was getting the car ready for a track weekend and noises from that area bothered me just a little .
