After 4 years of ownership, I have eventually got round to changing fuel filter as there was no previous history and with ~80k on the clock it was probably time. Correct - not before time it was the original ! How many more of these are still about - probably quite a few? Petrol and tank quality has come a long way over the years. I remember when fuel filters had glass domed tops so you could see what was going on and easily unscrew and clean filter!
