noise coming from gas tank?

[Kramer]

I have been doing some work to the Cobra with some updates etc. I am also trying to button up any loose ends while I have it apart.

Question. Since I have had the car, it seems like even the slightest movement creates a clicking noise coming from the tank area. To my knowledge, I always figured it was the fuel gauge/float moving in the tank. It is most noticeable when I move the car without starting it(i.e. rolling it around the garage)...it will rattle back and forth and eventually go away in a few seconds.

Is this normal? (I have even pushed on the car after returning from getting gas and it still clangs away for a second or two).

Gas gauge works...just want to make sure this is normal?

Thanks, Kramer

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 .

Thanks Bob - After looking at the tank pics on the ERA website I assumed it was something like this. Good to know it is nothing major.

If you can hear the doors clinking, your exhaust is too quiet.

(We changed to nylon flaps about a year ago so that there would be no questions like this... I still like the original design because of its Engineering Elegance. )

Maybe Peter left a hidden Morse Code transmitter in there with a message to "send food".

Get the same thing when the tank is less than full. Always figured it was the flaps in the tank.

A little known fact is that ERA's Peter P was Guglielmo Marconi's assistant when he was very young... Little Peter would hold the transmission wires, one in each hand, and act as a loud speaker for the morse code signal as the electrical charges came through the wires... it explains a lot about his current behavior if you know this fact about his early years. Others have electro shock therapy to control their behavior, Peter had his years ago.
