The Nitrous Pro-Flow Pro Series Fuel Flow Tool is a must for the nitrous racer. Use of this tool is the only accurate way to set flowing fuel pressure. To be set properly, fuel pressure must be set while fuel is flowing through the regulator at the same rate as when the nitrous system is activated. The flow tool works by attaching one end to the #6 fuel feed line, and inserting the proper size slip fit fuel/nitrous jet in the other end. The fuel supply is then turned on and fuel pressure is set while fuel is allowed to flow through the flow tool and into a fuel container. The tool includes an instruction sheet and jet chart.
