Fuel/Water separator service cycle

[Ranga]

I use a Donaldson P550088 fuel/water separator filter in the Defender 300Tdi. Any idea what the recommended service cycle is for one of these?

P550588???

I used to do mine every service and never bothered draining between, the sedimenter catches most everything.

Pretty sure i have the same one on the 6by just after the tank switchover solenoid. I change it every 10k but then I am running bio through it. Occasionally I open the drain screw and let a little out to see what's there.

IIRC, 20,000km for LR serive schedule of the fuel filter. Now I guess thats as long as the Dono meets the same specs as the LR filter.
