I picked up a spearco kit from a guy at work yesterday and it looks like its more complicated then it should be. lol. It has a tank, a pressure switch, and a alumnum heatsink that has a circut board in it and at least 8 wires coming in and out. I think I have figured out what does what, but I still see no need for the circut board. Does anyone have any info on these olf kits or a online manual?

thanks

Looks just like that pic I pulled from ebay. I guess its a Econo-Tronic?That tank/pump combo looks a lot like the universal windshield washer kit I got from Autozone when I made up my homebrew alky/H20 injection kit.

You could likely wire the pump up to a 'key on' power source, then use a Hobbs pressure switch to turn it on at 8-10psi. Mount a misting nozzle into the rubber intake line between the air filter and the throttle body. A mix of 50/50 distilled water and denatured alcohol worked great!:nod:

it has a pressure switch and all that. I just am wondering why it has the little circut board when I see no need for it on such a simple system.

is the pressure switch actually an analog sending unit to the electronic box rather than a digital switch like a hobbs?

it seems to be completly seperate and just screwed into the side of the box. wires run out the bottom and then into the circut board. I think I will run it just because it says spearco on it (lol), but would like to understand how it works before I trust my engine with it.

is the pump attached to the bottom of the reservoir? it looks a little small if it is. looks like a windshield washer pump. maybe you outta call spearco and see if you can get some documentation on the setup. im sure they have something that will tell you how exactly it works and how to hook it up.
