Nikki Propane Vaporizer / Regulator – NI16310-GU20A

This propane vaporizer and regulator is built by Nikki for its LPG fuel system, fitting Yale lift trucks running propane power. In an LPG fuel system, the vaporizer converts liquid propane drawn from the tank into vapor using engine heat, while the regulator steps that vapor down to a usable pressure before it reaches the engine's fuel mixer.

The unit weighs 6 pounds, a weight consistent with a cast metal vaporizer-regulator body that houses both the heat exchanger passages and the pressure-regulating diaphragm in a single assembly, which is the standard combined design used in most forklift LPG systems.

As the component responsible for converting and regulating propane fuel delivery, a vaporizer-regulator that develops an internal leak, a stuck diaphragm, or restricted vapor passages typically causes hard starting, stalling, poor engine response under load, or inconsistent idle. Because propane systems depend on stable regulated pressure to keep the engine's air-fuel mixture correct, a failing unit can also increase fuel consumption or cause rough running even when other engine components are in good condition. This Nikki unit is built specifically for the LPG system used on Yale propane-powered lift trucks.
