Hi,I had my fuel pump replaced recently and since then my fuel gauge and electronic readout work but are way out. It shows in the gauge as half full all the time even when empty,the electrical readout always shows 210 km if fuel left even when empty. Is it the sensor on the fuel pump or does it need calibrating. If it needs calibrating how do they do this?

Jeeps are famous for having problems with the fuel gauges. In your particular case, your vehicle's computer may simply need to be reset. You can follow the instructions in your owner's manual in order to do a computer reset. If this does not work, you will want to have the new fuel module inspected. The new pump/fuel module may have been faulty when it went in, or it may have been installed incorrectly. Good luck.
