wonder why no one has asked this question....... cant find an answer in searches
I never gave it much thought just got the spanners and go on with it
can anyone confirm the below
the hard line pipe nut size
at the banjo of the fuel filter
a nut into the filter / banjo with two washers was a 14 mm once
and is it 17mm at the fuel rail

The strap or clamp that holds the filter to the firewall has two bolts. The upper one has a 12mm head and the lower one 10mm. The banjo fitting that connects to the end of the filter with the flange (the end that should be pointed towards the passenger side of the car or front of the engine) is 19mm. The nut built into that end of the filter is 22mm. The banjo fitting that goes to the other end of the filter (the driver's side) is 22mm. The nut built into that end of the filter is 27mm. The banjo at the end of the fuel rail is 19mm.

just a note : people often find it very difficult to loosen these nuts. There is a simple way. What is needed are long spanners. Long spanners (up to a foot) dramatically increases the torque applied. Correctly fitting long spanners makes loosening the nuts very easy.
Short ones increases the possibility of damaging things as one struggles to apply the necessary force. I found a couple of long ones (very cheap) at a pawn/secondhand shop. I'm looking in time to buy some very long high quality ones from a tool shop. I see it as a good investment as the cost quickly offsets the cost of labour in having someone else do it for me a number of times.

My Ryco Z311 filter arrived by post today, a few days early, so I now have first hand experience of replacing an existing filter. Having the new filter in hand made it easier to measure and I discovered some errors in my post above, so have edited and re-written it with all necessary corrections. In particular, the nuts built into each end of the filter are actually different sizes, 27mm on one end and 22mm on the other.
The filter I was replacing must have been the original. It was a Bosch 086, Part No. 0450 905 601. The Ryco Z311 is identical in all dimensions.
The banjo fittings at each end were ridiculously tight, so I appreciated TS370000's comments above about using long spanners but apart from the force required, there was also a problem of insufficient clearance to apply much movement to the spanners. Fortunately, once "cracked", the banjo fitting bolts loosened up after only a fraction of a turn and could then be undone with fingers only.
When fitting the new filter, I found stubby spanners handy because they could be rotated further in the restricted space. This was particularly so at the passenger side end of the filter where I couldn't turn my longer ring spanner far enough to be able to advance it to its next flute.
Be sure to disconnect the battery before you start.

25-35Nm for bolts on both ends of fuel filter
