lets see if I remember.....
$140 for the pump (westmarine 4.0 GPM washdown pump)
$75 for tank (tank-depot 7 gallon flat bottom tank)
$50 additional parts (polyethylene glue, elbows, etc)
I know I know, its a bit pricey. Some guys are probably saying, 'no effen way I'm paying $300 for a wash down system when I could buy one for $30'. To those that may say that I say......................enjoy your insecticide sprayer.
