i dont even know where the pipe is,

l think you may find it attached to the base of your windscreen washer bottle. If not pop into Halfords and take a peek in the Haynes manual.
Hope this helps.

e-bay may have one, if not try your local scrap yard.if no luck you have to go to your local peugot dealer,

follow the pipe from the reservoir or the other direction from the jet nozzle, some times they are actually part of the filler cap

forget above.its under the plastic wheel arch linner just infront of the drivers front wheel.its attached to the water bottle.just changed mine

where you feel the water for the washers is the washer reservoir, on the bottom of the reservoir will be the pump it may be better trying to get to it from bellow the car
