2001 S60 - where do windshield washer pipes run?

[Duncx]

When I try washing the windshield I see a ton of fluid run out from behind the bumper. Means i run out of fluid in no time at all.

I'm presuming that a pipe has split on its way to the headlamp washers but where do the pipes run and how do I access them? I assume I have to remove the front bumper but how?

Any help would be great. Cheers.
