Just figured id post this up. (couldnt post in DIY section because i dont have access to)
I did this a few years back and since then ive learned so much more.
It is a great tool to give you ideas to incorporate the pump and use the stock windshield washer reservoir

I later realized that the nozzle placement wasnt ideal since my throttle body started sticking and had to replace it. I live in Michigan, and the extreme temperature fluctuations cause more wear and tear. Some have had their water/meth systems setup like this for years until running into problems.

Anyway, heres the link.
