after a long time with the noise not recurring, it started up again this evening during a drive.

on a hunch, after I'd noticed that I was below half a tank of gas, I went to the local gas station (humming sound quite evident) and filled up the gas tank.

driving home, no humming noise at all!

I wonder what condition, when the tank is below half full, that causes that humming noise....it appears to be quite a piece of work to get to the check valve on the gas tank too....

so maybe I'll top her off when she's at half tank from now on.....
