So, my car recently had the fuel pump changed. What I noticed now is that the fuel level needle moves up when I accelerate. If doesn't make a big jump, just a little bit, but it's very noticeable. Like it will go from reading a bit less than a quarter full to a bit more than a quarter. Then if I take the foot off the gas it goes back down. Is that normal?
