How to drain fuel from W205 diesel

[zaen1]

Hi all, can anyone tell me the best way to drain the fuel from a W205 , car is a diesel and ive put almost full tank of petrol in it, luckily petrol station is less than a half minute drive so hoping no damage has been done

you have elctric primer pump, which engages when ingnition on. Never done but I think fuel filter incoming hose should be good place to open

I didn't think you could do this with a W205; I've tried (absentmindedly) a couple of times and it just won't accept the nozzle. Need to be careful draining petrol, though!
