This is probably super simple but I can't seem to find any info on the Fuel Filter water trap/ how to drain it/ or even replace the fuel filter at 48 month service?

 

You have a diesel engine ?

 

Ah, got it. Water trap is only for diesel engines. Makes more sense.

For replacing the fuel filter, should be for all petrol engines too, no?

 

My research into a fuel filter replacement for the new Defender, which has yielded no results, leads me to believe that they have gone the way of most modern cars. Meaning there is no replaceable filter. Porsche engines have a lifetime filter, needing no replacement. It is part of the fuel pump assembly, which is submerged in the fuel tank, and is not replaceable. My ‘08 Boxster has this setup. Unless I’m mistaken, I believe the Defender has a similar system

 

If this is true, then excellent. Hopefully it really means lifetime unlike other filters and other vehicles.
