Hey Vansolo,
Nice work on the pump and thanks for your post. I just had to do the same thing today and your post and pictures came in very handy. I have an 03 HL and was able to get the washer pump from the dealer, however, mine ran me $75.
I took a few pictures myself and thought I'd add them to help anyone else in our same predicament.
(note: you may have to click on my photo album to see them if they don't upload into this message)
To anyone who is unsure about doing this themselves, it is really straight forward. The pump literally just pull right out. You won't break anything, as it isn't screwed in or anything. The hardest part is just getting to it, and even that was just a few screws.
Thanks again for your valuable post.
