Extending the Fuel Tank Capacity for Generators

As a portable generator owner, you may have come across the need for running your generator for extended periods of time without having to constantly refuel. One solution to this problem is to add additional tank capacity to your generator. In this article, I’ll go over the different options available for adding additional tank capacity to a generator, as well as the pros and cons of each option.

Adding a larger fuel tank to the generator

One option for adding additional tank capacity to a generator is to add a larger fuel tank to the generator itself. This can typically be done by attaching an additional tank to the side of the generator, increasing the overall fuel capacity.

For example, if a generator has a fuel tank capacity of 2 gallons, adding an additional 2-gallon tank will increase the generator’s fuel capacity to 4 gallons. This would increase the running time of the generator before needing to refuel.

This option is relatively simple and straightforward, as it does not require additional equipment or modification to the generator. However, it can add weight and size to the generator, which may make it less portable.

Connecting multiple fuel tanks

Another option for adding additional tank capacity to a generator is to connect multiple fuel tanks to the generator. This can be done by connecting the tanks in series so that as one tank runs out, the generator automatically switches to the next tank.

For example, if a generator has a fuel tank capacity of 2 gallons and you connect two additional tanks with a capacity of 2 gallons each, this would increase the generator’s fuel capacity to 6 gallons. This would increase the running time of the generator before needing to refuel.

This option can be useful if you need to run the generator for extended periods of time and don’t want to have to constantly refill the fuel tank. However, it can be more complex to set up and may require additional equipment or modification to the generator.

Using a fuel transfer pump

Another option for adding additional tank capacity to a generator is to use a fuel transfer pump to transfer fuel from an additional tank to the generator’s fuel tank. This can be a useful option for those who want to use a larger fuel tank than what the generator can accommodate.

For example, if a generator has a fuel tank capacity of 2 gallons, but you want to use a larger tank with a capacity of 5 gallons, you can use a fuel transfer pump to transfer fuel from the larger tank to the generator’s fuel tank. This would increase the running time of the generator before needing to refuel.

This option can be useful if you need to run the generator for extended periods of time and don’t want to have to constantly refill the fuel tank. However, it can be more complex to set up and may require additional equipment or modification to the generator.

Using a Fuel Tank Extension Hose

Some generators come with a fuel tank extension hose which allows users to connect external fuel sources like large fuel cans or drums to the generator. This can be a useful option if you have a large fuel source and you want to use it for a generator. This option is relatively simple and straightforward, as it does not require additional equipment or modification to the generator.

Conclusion

There are several options available for adding additional tank capacity to a generator. Each option has its own pros and cons, so it’s important to consider your specific needs and preferences when deciding which option is right for you. Keep in mind, that before attempting to connect additional tanks, it’s important to check the generator’s manual or consult with the manufacturer, as doing so may void the warranty.
