Why an External Fuel Tank for My Generator Is Necessary
From my experience, having an external fuel tank for my generator is essential for several important reasons. First, it significantly extends the run time of the generator without the need for constant refueling. This is especially crucial during power outages or long work projects where uninterrupted power is a must. Instead of worrying about the generator running out of fuel every few hours, I can focus on what matters most.
Another reason is safety and convenience. With an external tank, I can store fuel in a safer, more accessible location away from the generator’s heat and exhaust. This reduces the risk of spills or fire hazards. Plus, it makes refueling quicker and less messy since I don’t have to open the generator itself each time.
Lastly, an external fuel tank helps keep the generator running smoothly. Constantly stopping to refuel can cause wear and tear on the engine, but with a steady fuel supply, the generator operates more efficiently and lasts longer. Overall, adding an external fuel tank has been one of the best upgrades I’ve made to my generator setup.
My Buying Guides on External Fuel Tank For Generator
When I first started looking for an external fuel tank for my generator, I quickly realized there’s a lot to consider. I want to share what I’ve learned through my experience to help you pick the right one for your needs.
Why I Needed an External Fuel Tank
My generator’s built-in fuel tank didn’t last long enough for extended power outages. Adding an external fuel tank meant I could run the generator longer without constantly refilling. If you’re like me and rely on your generator during emergencies or long projects, an external tank is a smart investment.
Capacity: How Much Fuel Do I Need?
One of the first things I checked was the tank capacity. External tanks come in a variety of sizes, from small 5-gallon containers to massive 50-gallon setups. I assessed how long I wanted my generator to run and how often I was willing to refill. Bigger tanks mean longer run times but also take up more space and can be heavier to move.
Compatibility with My Generator
Not all external fuel tanks work with every generator. I made sure to check the fuel type (gasoline, diesel, or propane) my generator uses and found an external tank designed for that specific fuel. Also, I looked for tanks that had compatible connectors or adapters to ensure a secure, leak-free connection.
Material and Durability
I wanted a tank that would last, so I chose one made from high-quality materials like heavy-duty steel or thick polyethylene plastic. Steel tanks tend to be more durable but can be heavier and prone to rust if not properly coated. Plastic tanks are lighter and corrosion-resistant but may not be as tough in harsh conditions.
Portability and Size
Since I occasionally move my generator setup, portability was important. I looked for tanks with handles or wheels for easier transport. If you plan to keep your tank stationary, size and shape might be more important than portability.
Safety Features
Fuel is flammable, so I prioritized tanks with built-in safety features. I chose tanks with secure caps, vents to prevent pressure build-up, and sturdy construction to prevent leaks. Some tanks also come with grounding options to reduce static electricity risks.
Ease of Installation
I wanted a tank that was easy to hook up without needing special tools or professional help. Many tanks come with complete kits including hoses, clamps, and fittings. Reading reviews helped me find options that users found simple to install.
Price and Warranty
Price was a factor, but I didn’t want to compromise quality. I compared prices across different brands and checked what kind of warranty was offered. A good warranty gave me peace of mind in case anything went wrong.
Final Thoughts
Buying an external fuel tank for my generator made a big difference in how I manage power outages and outdoor projects. By considering capacity, compatibility, materials, safety, and ease of use, I found a tank that fits my needs perfectly. I hope my guide helps you make a confident choice for your generator setup!
