Yesterday I noticed this weird humming noise coming from the center of the car. I didn't pinpoint the sound, but when I put my hand on the inline fuel filter its vibrations matched with the sound. And when I filled up with gas, the sound went away.
So I'm guessing it was because I was low on fuel, but it only took 12.6 gallons to fill up and I know I have a 16 gallon tank. And my previous 91 740 never made those noises even when it was on E.
So what could be going on here?
For some extra info that may or may not be pertinent back in July I had to clean out the tank and replace the in tank fuel filter because it had been sitting for 7 years. And two weeks ago I replaced the inline fuel filter. Also, my gas gauge doesn't work (no signal at sensor wire) so I have no idea what it would have read when the noise was going on.
