What fuel accessories do I really need. GU 3.0TD

Stick with the standard stuff Andrew. Nissan has spent a lot of money perfecting it for your car. And if the car is still under warranty replacing filters with any thing but Nissan approved will void warranty.

Andy,

The first symptoms were the ECU (orange engine light) light coming on and a loss in power. First actions were to drain the filter and after doing this on about 5 occasions over the day I changed the filter when reaching camp. After the change of filter the symptoms were gone.

Regards,

Dave

Andrew,
One thing which you can add and does not void your warranty is a water trap upstream of the original filter.
I added a water trap (first consulted with Nissan) with a clear glass which allows you to see water, colour of the fuel and sediment without even draining or touching anything, just opening the bonnet to check oil and glance at the fuel quality.
The water trap has a drain tap which needs to be drained every service.

I got it from Cooma diesel but any diesel specialist can supply one, be aware that this is not a change of the filter and it is not an extra filter.
The pump uses the fuel for cooling and lubrication, therefore the factory will void warranty if you add anything that will change/ restrict the system, but a water trap does not.
It is simply a canister (clear) with a swirl design so that fuel enters, swirls and the water and heavy sediment is separated before it enters the filter.

whatever you do, stick with the original filter. It is designed to keep the fuel clean and this is critical to the fuel pump. The reason is clogs with bad fuel is that it is doing its job.
