    My first line of attack with this problem would be to change the fuel filter. It's so frequently overlooked by garages when performing a service.

    It's also possible that your fuel tank has been contaminated by 'diesel bug': https://en.wikipedia.org/wiki/Microb...of_diesel_fuel
    This sludge floats around in the tank and can block pipes and filters. It may be that a culture of microbes is floating in the tank, causing a blockage when half the tank has been used.

    Cheers,

    Tom

    Definitely no pump in the tank. I've been in mine 3 times to change the sender. Two senders from breakers and one OEM and I still don't trust the gauge. Carry around 5ltrs of diesel.
