This is probably a stupid easy question for you guys. But I'm new to owning a 280z. I have a 78 by the way. My question is I'm unfamiliar with how the gas gauge is supposed to operate. I know it's a float unit and I've never owned a car with one before. Mine for example right now is on just above slightly a half a tank. But while I'm driving or even sitting still it moves a little, not much, just sometimes it's a half, then maybe a few seconds later it's just above a half slightly where it finally rests. When I drive it seems to go up when I stop etc. Is this normal, and due to the float, or should the gauge be still always and not have a lot of movement.?? I know it's a dumb question but if your share some insight into what's "normal" operation for a 280z fuel gauge I would really appreciate it. --
