Nikki Propane Regulator – NI16310-GZ560

This propane regulator is built by Nikki for its LPG fuel system, fitting UniCarriers and Crown lift trucks running propane power. The regulator's job is to step down the pressure of vaporized propane fuel to the stable, usable pressure the engine's fuel mixer needs, smoothing out pressure swings as the tank empties and engine demand changes through a shift.

The unit weighs 6 pounds, a weight consistent with a cast metal regulator body housing the internal diaphragm and pressure-adjustment mechanism common to forklift LPG regulators.

As the component responsible for maintaining stable fuel pressure, a regulator with a worn or torn internal diaphragm typically causes inconsistent engine power, stalling under load, hard starting, or a rough idle that varies unpredictably. Because the regulator sits directly in the fuel delivery path, any internal leak also raises the risk of unmetered propane reaching the engine, which is why a regulator showing performance symptoms should be addressed rather than worked around. This Nikki regulator is built specifically for the LPG systems used on UniCarriers and Crown propane-powered lift trucks.
