Kia Hyundai 1.0 Lpg Pressure Reducer

The pressure reducer with the original OE code 3312004300 is a fundamental component of the LPG system installed at the factory on certain Hyundai and Kia models. The main function of the reducer is to lower the pressure of the LPG gas coming from the tank, transforming it from a liquid phase to a gaseous phase and stabilizing it for injection into the engine. This component works in conjunction with the electronic management system of the LPG supply, ensuring the correct fuel delivery under all operating conditions.

Technical characteristics

The OE 3312004300 reducer has the following main features:

• Type: LPG pressure reducer
• Application: LPG systems factory-installed on vehicles
• Equivalent internal code: GPLRG012N
• Transformation phase: from liquid LPG to gaseous LPG
• Cooling: water-cooled, via connection to the engine cooling circuit
• Structure: metal body with internal membranes and valves
• Regulated outlet pressure: low pressure (typically between 0.9 and 1.5 bar)
• Integrated sensors: can incorporate or interface with gas temperature and pressure sensors

DIPA offers a range of original and aftermarket spare parts of equivalent quality.

Functionality

The pressure reducer manages the conversion of LPG from liquid to gaseous state in a controlled manner, ensuring the engine receives a constant and correct pressure for injection. The reduction phase occurs through one or more expansion chambers, with internal membranes and valves that regulate the flow based on the engine's demand. The transfer only occurs when the engine is at temperature and pressure conditions are stable. The engine's cooling circuit prevents the reducer from freezing due to gas expansion.

DIPA recommends always verifying the compatibility of the spare part before purchase.

Defects and causes

Among the most common faults found in the LPG pressure reducer 3312004300 are:

• Gas leak: caused by wear of internal membranes or gasket failure
• Incorrect pressure regulation: caused by stuck valves, blockages, or mechanical damage
• Reducer freezing: if the cooling circuit is inefficient or contains air bubbles
• GPL supply blockage: caused by impurities in the gas or clogged internal filter
• Delivery fluctuations: due to inlet pressure variations or internal malfunctions
• General wear: after many kilometers or years of use, internal components lose efficiency

These faults can cause automatic switching to gasoline, engine warning lights, power loss, or difficulty starting when cold.

Final conclusions

The pressure reducer with OE code 3312004300 is an essential component for the safe and efficient operation of factory-installed LPG systems on Hyundai i10 and Kia Picanto models with 1.0 three-cylinder engines. Its wear can lead to significant fuel supply and engine performance issues.
