So I drive an '01 Oldsmobile IntrigueGX and it has a the EVAP OBD-II code P0441. Before I purchased the vehicle ... I got the car inspected for defects and provided a list of things the owner should either take off the price or fix himself. He agreed to take off the price partly because he was desparate to get rid of it but also because I had the mechanic who worked on it quote insane fix prices. Ain't I a little stinker ...

Anyway, about the code, the EVAP system is something that is preventing me from passing an inspection and I think it might have something to do with the float in the gas tank. I'm not quite sure it could not actually be leaking evaporated gas from somewhere but because I don't want to spend money on diagnosing it again ... I'm willing to see if one thing fixes the other.

My question is, could the erratic behavior of the fuel gauge be causing the code? Could it be, that the float could be broken, hence leaking gas, hence causing the code?

I understand that they all could be totally unrelated and I purchased a lemon. I understand that they could be independent incidents but indulge me here. Fuel gauge could be broken, causing the leak, setting off the code, is this possible?

The fuel gauge moves up and sits at full at all times uinless when the car has just been started and was cold. It also moves up and down slightly according to the general inclinitation of the car. This is why it led me to believe it's the float and not the ground wire.

Diagnosing the code will consist of the mechanich draining my fuel tank. Sealing it and blowing smoke through the entire fuel system. Any leak of smoke will be the cause of it. This is also an expense I want to see if it is worth risking a guess by not doing it.

I already reset the code and drove it for a week. It came back on when my fuel tank was empty but the gauge was sitting at full!!

What do y'all think?:
