I just had this issue on my 2002 V70
Bought the car on Xmas Eve, but seller didn't mention the corroded filler pipe.
So I promptly flooded a petrol station with litres of fuel
Tried to fix it myself but I don't have a ramp or a lift.
And I was 200 miles from home...
My local garage (PTA in Bromley) were awesome.
They obtained the part (£10) and fitted it (a further £110).
And now I can fill the tank instead of the forecourt
