For maximum nitrous power and engine safety, nitrous kit manufacturers tune their systems with various jet sizes and fuel pressures. While installing the recommended jet is simple, correctly setting your nitrous system's fuel pressure can be a real challenge if you don't have the right tool.

ZEX created the Fuel Flow Check Tool just for this purpose. By temporarily attaching it to your fuel solenoid's feedline, you can simulate the normal fuel flow your nitrous system sees when it is activated. Once your fuel system is in this "flowing" condition, you can easily and accurately adjust your fuel pressure regulator. Once the regulator is set, you simply remove the tool, reconnect your fuel line to the solenoid and you are all set for the track.

The ZEX Fuel Flow Check Tool includes a laboratory quality, liquid filled, 0-15psi gauge, -4AN and -6AN adapters, calibration jets and all necessary fittings for easy assembly. You simply won't find a more accurate or easy-to-use tuning tool for your nitrous system.
