Well I ended up getting a pair of the water sprayers off of mpaone so I got started on the actual tank and pump. I looked around and didn't find anything small enough tank wise but with a good pump. Well at a local junk yard my search ended. The rear washer tank and pump from a Nissan Terrano/Pathfinder from the late 80's. Reason is that because it sits in the trucks engine bay and pumps all the way to the rear its incredibly strong and it doesn't use a massive tank either. Just for fun we set it up in the garage hooked up temp. to a friends car and managed to shoot water from the stock hood sprayers 15ft. So I'd say that's plenty strong enough for a sprayer kit. Now I just want to get ahold of another pair of nozzles and a splitter for the GC8 plus find a way to seal the splitter to the TMIC.
