I had it done by a shop and it took a little bit over 4 hours. We had a small incident with the tank (not a BMS one) and we had to repair the connection elbow so it took a little bit longer than expected.
I chose to place the tank next to the battery, the pump on the foam platform that lays over it, and we routed the wires and meth line under the car and inside the front fender before entering the engine bay. I am pretty satisfied with the install, nothing apparent in the trunk, and in the engine bay the hoses were passed through black plastic pipes so it looks almost stock. I haven't tried it yet, too many cars on the way home.
