Filter in wash bottle, had that before, it was full of slimy gunk. Depending on model, access is had by taking off the front wheel arch liner, so its wheel off, remove liner, then its a fiddly fiddly job to get the pump off IIRC. Very little room to get your hands in, but no special tools required.
