Apologies if this question should go in the Technical help section, but given that I'm in the middle of trying to prep my bike for the big trip (UK-Oz) I felt it might be more appropriate here.

I've just been reading through the Adventure Motorcycle Handbook (my bed time reading these days!!) and it mentioned that it might be worth thinking about an in-line fuel filter for riding in more dusty/sandy parts of the world.

To be honest I'd thought about Air filters and oil filters, but don't really know what an in-line filter is, where it goes or whether i need one?

Any advice, particularly from those in the more dusty/sandy parts of the world would be greatly appreciated....

thanks in advance
