Can anyone tell me how to remove the rear washer jet from the top of the boot. I think there is a load of sludge in the tube behind it which has been sucked up from the tank as it is blocked and need to remove it to blow the tube through. I don’t want to break it as it looks as if it has never been taken out since it went in. I have cleaned out the tank and that is now clean but the hose is still blocked, if I can get the jet off the end I can hopefully blow it all the way through.  It looks as if there is a black plastic bit which is mounted on top of a rubber backing but before it goes through the hole in the tailgate.

any help greatly appreciated.

they have like a fishhook arrangement on the rear , you would need to poke something to depress those them prise up ....when ive removed them they never clip back in tight so i would suggest finding a new one before possibly ruining it
