With its durable construction, easy-to-use design, and compatibility with various Generac models, the B3479 NOS Unloader is a must-have accessory for any Generac generator owner.

The Generac B3479 NOS (Nitrogen Over Pressure) Unloader is a fuel delivery component designed for use with Generac air-cooled standby generators. It facilitates the transfer of propane from the bulk storage tank to the generator's fuel tank through the use of nitrogen to pressurize the system and maintain gas tight seals. Here are some potential pros and cons of purchasing a Generac B3479 NOS Unloader:

Pros:

1. Ensures proper fuel delivery: The Generac B3479 NOS Unloader utilizes nitrogen to maintain a constant pressure within the fuel system, preventing fuel vaporization and ensuring consistent fuel delivery to the generator.

2. Prolongs fuel system life: By preventing fuel vaporization, the unloader can help reduce the wear and tear on the fuel system components, leading to a longer lifespan.

3. Simplifies fuel system refueling: The unloader eliminates the need for manually priming the fuel system during refueling, making the process quicker and more convenient.

Cons:

1. Cost: The Generac B3479 NOS Unloader is an additional investment in the fuel system, which can add to the overall cost of owning and operating a Generac standby generator.

2. Installation complexity: Installing the unloader requires specialized knowledge and tools, making it a potentially more time-consuming and involved process compared to a standard fuel system installation.

3. Potential for leaks: The use of nitrogen within the fuel system increases the potential for leaks, particularly if the system is not properly sealed or maintained.

In conclusion, the Generac B3479 NOS Unloader offers several advantages, including improved fuel delivery, prolonged fuel system life, and simplified refueling. However, it also comes with potential drawbacks, such as increased cost, installation complexity, and the potential for leaks. Ultimately, the decision to purchase a Generac B3479 NOS Unloader depends on individual circumstances and priorities. If consistent fuel delivery and longer fuel system life are top priorities, the investment in the unloader may be worthwhile. However, if cost and installation complexity are major concerns, alternative fuel delivery methods may be more suitable.
