I got the tank from summit with
1 fitting being 3/8 one 1/2
3/8 line was for over flow vent and a short peice that went to the rad.
The 1/2 came off the bottom. It had this factory Tee on the truck. Cut all that off. Re Tee'd it and barley squeezed it back onto the water pump.
Well I've decided to just use the switchspeed for now. They aren't releasing a Vu4 with threaded ports anytime soon from what I can tell. So I'm just using 3/8" Valves with hydraulic line, accuair switchspeed, and a avs digital gauge setup. I already bought some Slow downs/valve mufflers for cheap on eBay. I can put together a full Valve setup with hydraulic line for the cost of the vu4 by itself.
