Fuel filter replacement

[nrobinson]

Just about to replace my fuel filter on 2003 XC90. The filter is is the paper cartridge type. I'm hoping it shouldnt cause any dramas but have been caught out before with the jobs that are supposed to be easy !

Referring to the Haynes manual as i couldn't find anything on Vida, the write up starts by saying do not change if the tank is over 3/4's full - typically !! mine is full to the brim at the mo, and not likely to be used much until the filter is done. I could really do without messing around draining fuel off.

Can anyone tell me the reason it shouldn't be done with more than 3/4 tank. Is it because it will induce fuel siphoning or similar?

Also whilst on the subject how durable are the drain taps on the filter housing? I'm assuming they are plastic? The last one I did on an older landrover snapped off when trying to undo it and i wish i had left it alone and just removed the complete housing instead of draining.

Thanks
Nick
