G'day, the fuel gauge in my au ute goes to full then down to empty when I start the car, apparently this is a common Problem and ford released a tsb to adjust the sender/float, does anyone know how to do this? Thanks

Just to add the ute has a Delphi pump in it as the original one was not working when I bought the car

For anyone who is interested my gauge fault appeared to be a crook terminal in the connector at the top of my fuel pump, hope this is helpful
