If you are relying on the gas gauge to tell you how much fuel you have left, and you have a replacement tank sender, it is necessary to bend the float arm to calibrate the reading. If that doesn't fix it, the float is probably hitting a baffle in the tank, and the flange of the sender must be rotated. We always install a ground wire to one of the screws on the sender and connect it to a known good grounding point. If you are using a plastic tank, this is vital.
