changing the add blue tank

[newmandrylining]

i am now going to attempt to change the add blue tank myself on my 2018 1.6 hdi  van . i found a second hand tank on ebay £140 from a 2015 multi space so alot cheaper than the £880 from the dealer for a new tank. if any body has any tips on removing and refitting please let me know.

Just get a new one under warranty?

They wont replace under warrenty because of the 5mm hole i put in it . £880 for a new tank plus fitting all drained down but cant get off due to fuel filler pipe stopping the tank dropping down
