on the freelander under arch shelf there are 3 items, low pressure pump round item with in and out connectors and electrical plug a round silver cylinder this is the fuel filter in at one end out at the other and a round black fuel filter ( i believe to trap any moisture ) just needs cleaning by undoing the butterfly plug. if you are replacing the pump then change the filter at the same time might be a tight fit in the holder, once done the system is self bleeding just turn the ignition on and leave until you hear the air going back into the tank
