Never used G-man 5qt tank, haven't even drilled it for the line out yet. It also comes with two float switches for your washer bottle, a windshield washer lift pump, and relay system to turn the lift pump on and off automatically. This system is based off of Joe Perez's auto filling windshield washer bottle system for your W/I https://www.miataturbo.net/methanol-water-injection-22/different-sort-water-tank-setup-9256/ I was building the system with GM weather pack connectors. You get enough connectors to complete the wiring job. Also has a lead for a dash light to tell you when the system is on.
