converting your generator to LPG: comprehensive guide

LPG is used as an alternative fuel source. BISON will reveal why so many people are starting to use LPG and how to convert your generators to LPG.

Table of Contents

Generators are vital machines that we rely on to provide us with stability and comfort during power outages or when conventional power supplies are unavailable. A typical generator uses conventional fuels such as petrol and diesel. However, it is becoming increasingly apparent that there is another competitor in the field of fuel sources: liquefied petroleum gas (LPG).

In this blog, LPG is used as an alternative fuel source. BISON will reveal why so many people are starting to use LPG and how to convert your generators to LPG.


Advantages of using LPG as generator fuel

The use of liquefied petroleum gas (LPG) as a fuel for generators has many advantages and is therefore becoming increasingly popular.

1. Reduced costs

The economic advantages of LPG are undeniably attractive. Although the initial investment in converting to LPG incurs additional costs, the savings are considerable in the long run.

Compared to petrol, LPG is usually more cost-effective per litre or gallon. The price of LPG is relatively stable, which means it is unlikely to fluctuate significantly.

2.  Environment

One of the major advantages of LPG over conventional fuels such as petrol or diesel is that it is environmentally friendly.

The cleaner combustion of LPG greatly reduces the risk of environmental pollution, making it a more sustainable fuel source.

3. Reliability

In some areas, LPG is more readily available than gasoline, making it a more practical option for running a generator.

LPG generators tend to be more reliable than gasoline generators because they are less affected by problems such as stale fuel or clogged carburetors. Liquefied petroleum gas engines can also reduce wear. Reduce carbon deposits, extend engine life and reduce maintenance or service interruptions.

Other notable benefits include ease of storage and safety considerations. Liquefied petroleum gas can be safely stored in tanks with minimal risk, reducing the potential for leaks and contamination associated with liquid fuels. Additionally, LPG generators tend to have a longer shelf life than gasoline generators, making them better suited for infrequent use, such as emergencies.

4.  Reliability

LPG generators run much quieter, which is a boon for people living in residential or quiet areas.

How to convert a gasoline generator to LPG

To convert a gasoline generator to LPG fuel, follow the steps below. Before starting, make sure you have all the necessary materials and tools.

Materials and tools required

Step-by-step instructions

#1 Safety First

Ensure that the generator is placed in a safe, well-ventilated area and turned off completely. Do not attempt to modify a generator that has just been run as parts may still be hot.

Ensure the generator is turned off and disconnected from any power source before starting a conversion. Also, make sure the gas tank is empty.

Remove the air filter: Locate the air filter housing on the generator and, depending on the fastener used, use a screwdriver or wrench to remove it. Store the screws or bolts safely, as you will need them later.


#2 Disconnect the carburetor

Use a wrench to disconnect the fuel line from the carburetor.

Remove the bolts or screws holding the carburetor in place.

Carefully remove the carburetor from the engine and set it aside.

#3 Installing an LPG conversion kit

An LPG conversion kit should include a regulator explicitly designed for your generator. Use the hardware provided to connect the conversion unit to the designated mounting location on the generator. Make sure the adjuster is securely fastened.

#4 Reinstall the air filter

Put the housing back in place and secure it with the original screws or bolts.

#5 Connect the LPG fuel tank

Follow the instructions included with the LPG conversion kit to connect the LPG fuel tank to the regulator. Make sure all connections are tight and secure.

#6 Test the generator

Turn on the LPG fuel supply and start the generator according to the manufacturer’s instructions. Check for leaks around the connections and listen for any unusual sounds.

If everything works fine, you have successfully converted your gasoline generator to LPG fuel.


As we explore in this article, there are many benefits to converting your generator from gasoline to LPG.

converting your generator to LPG FAQ

No, gasoline generators are not safe to operate on LPG without modification. Gasoline and LPG have different properties. Liquefied petroleum gas is stored as a pressurized liquid, while gasoline is a liquid fuel. Gasoline engines are designed for the specific way gasoline burns.

Each machine has slightly different characteristics, but as a rule of thumb, an LPG-converted machine will use 0.4 kg of LPG per kW/h of electricity generated.

While not cheap, the main benefit of choosing a dual-fuel generator is that the two fuel tanks of a dual-fuel generator ensure that power is available daily and in emergencies.
