Fuel Filter

We have run a pre filter on our D4D hilux for the last 3 years for the same reason.

The type we use has a glass bowl at the bottom that is used as a water trap.

On our last big trip a few months ago we were about 50K out of Kings Canyon and the factory fuel filter light came on warning of a restriction.

We replaced the factory filter first...it was the oldest filter been on since new, reset the warning light but 100k later the light came on again.

Replaced the primary filter, reset the light and alls good.

So it seems the primary filter did it's job.

It's cheap insurance.



On another note we always try and buy fuel a large truck or popular fuel stop, this is one of the reasons behind us being able to carry 330 lt's of diesel in tanks if needed.....we can be more selective on where we buy diesel.

I about to fit a Water Watch device to my D40 Navara. Had a bad experience recently with some contaminated diesel and decided that $500 or $600 is much cheaper than rebuilding the pump, rail and injectors in my common rail turbo diesel.
