correct the pump itself is approx 100 bucks.. we have the retail chains here called farm&fleet and tractor supply which it can be purchased @..
your motor will be an additional cost ..electric or gas.. as this is always the case
Thanks. Do you have a place and part number for the spray tips? I am going to build one of these with the electric motor like you got. I like the idea of it being quiet. And to hear how one of these will spray better than a trash pump...that's awesome. I would love some pics/links of all the components. You can email me if you want. Thanks again.
