My Ride: 2000 328ci
Fuel gauge reads low after changing gas cap

I've got a 2000 328Ci. While working on the car, which included replacing the gas cap, I had the radio on which drained the battery. I tried to start it but just got the flashing headlights. So after a jump, it started right up and I took it for a 30 minute drive to recharge the battery.

The problem is that my fuel gauge read about 1/8th of tank and the amber light came on too. But as I drove the car the fuel gauge went up past 1/4.

When I start the car I hear some noise in the right rear of the car and I assume it's the vacuum pump for the fuel system.

Any ideas on why the fuel gauge is not reading correctly?

My next step is to fill the tank up with gas and see if the gauge reads full. If not, then I'll remove and reset the fuse for the instrument cluster.

Well, not sure why it happened in the first place - possibly because I went too long with the old cap? Anyway, filled the car up and the gauge reads full and seems to be in good working order. But it was sure nice to see the gauge go up as I drove for a change.
