I'm new here have just got a Citroen C8 on trying to use the rear screen wash I noticed it wasn't working. Inititially I thought it was the holes in the rear wiper blocked. I could hear the pump working but still not water through the rear screen wash. I then opened the boot and noticed a puddle of water near on the driver side back row seatbelt. I removed the small panel and noticed a black hose had somehow become detached from the pump or something. How do I locate this to refit the hose.
