I replaced the fuel filter on my D2 at c 103k miles and this was probably the first time it was done. In my view a filter is put there for a purpose and so it follows that it should be replaced after some period of use. Given the cost benefit (i.e. how much does it cost ( approx £10) against what can go wrong if it doesnt do its job) it just seems sensible to change it.
For interest sake I cut mine open and it was discoloured showing that it had been doing its job. The last photo show the filter paper cut into two sections the lower of which shows the outer side all dark and contaminated and the upper section the downstream side relatively clean. How much longer life it had I cant say but you pays yer money and takes yer choice as they say.
