After the bottle brackets were installed, it came time to assemble the bottle fittings and install the bottle itself. We placed the bottle on a bench and carefully installed the nitrous pressure gauge, pressure relief valve, and heater solenoid. Of interest here was how Lacko positioned the gauge. In the mockup we did before, he checked all the angles of the valves and such on the bottle and put the gauge in a position where it was very easy to read when he looked at it in the bed. Once everything is tight on the bottle, install it in the truck.
