I fixed it after your post, just a day or two ago. It was super useful, although I haven't calibrated the fuel gauge yet. I figured I would fill up the tank to full and calibrate it that way. But when I removed the fuel level sensor i noticed the gas was very low and when I put the cluster back together it had the "low fuel" symbol lit up for the first time. This makes me think that the issue has been fixed, but i will confirm later on.
I saw the smoked bulbs but just decided to replace them regardless because I didn't know where to get smoked bulbs. Though maybe giving them a light coat of black spray paint would smoke them? Either way the new bulbs light up the cluster way better than before so I have no complaints.
