My fuel gauge works, kind of. The problem is it's not always accurate. Sometimes after I fill up and I drive for a bit the fuel gauge will drop down to a half a tank pretty quickly and then sit there. And then it will eventually start going down. It always goes down faster then what I actually using fuel. Another thing it does is that after you fill the tank it takes quite a while for it to climb all the way to the full mark. I have gotten to the point where I just use the mileage for knowing when I need to get gas.

Would this be more of a fuel gauge issue or more of the float / sending unit at the tank? And what would be the simplest way to check or troubleshoot the problem?
