How to Safely Store Fuel for Your RV Generator

For many RV owners, you won’t have to worry about electrical needs because the RV parks will provide those types of amenities. However, if you like to carve your own path or want to be prepared for anything, it’s never a bad idea to have an external generator.

If you own a generator or are planning to get one, it’s crucial to understand how important it is to keep it fueled for your outdoor excursions. Still, even once you have a handle on that, you’ll still need to know how to manage fuel storage, as not doing so properly can present unique challenges for safety and efficiency. Whether you’re safeguarding your supply over the winter or preparing for your next camping trip, properly storing and handling fuel is essential to both protect your equipment and ensure your safety.

This guide will walk you through the detailed safety tips for storing your RV’s generator fuel while also covering some essential advice on using it correctly. By following these steps, you can enjoy your RV adventures without worrying about fuel-related mishaps.

Know the Types of RV Generator Fuel

Before jumping into storage tips, it’s important to understand the different types of fuel you may be working with. RV generators are typically powered by three main fuel types, and each has specific considerations for handling and storage. Knowing this information is key to safely handling and storing it.

Gasoline

Gasoline is a common choice for RV generators because it’s readily available and affordable. However, it can be highly flammable and volatile if improperly handled, making appropriate storage a priority. It’s also important to note that gasoline has a limited shelf life of about three to six months, so rotating your supply is imperative.

Diesel

If you didn’t know, RV diesel generators are also a common option available to RV owners. This is great because diesel fuel is less flammable than gasoline, making it a safer option for long-term storage. It is often the fuel of choice for larger RV generators. However, diesel can degrade over time due to exposure to water or air, so preventive measures, such as adding stabilizers, are necessary.

Propane

Propane is a convenient and cleaner-burning option for some generators. It is typically sold in pressurized tanks, which makes it easier to manage than liquid fuels. However, improper storage or usage can lead to leaks, which pose serious safety risks.

Safety Tips for Storing Fuel

Now that you know the differences between the types of fuel, it’s time to learn how to safely store your RV generator fuel. Doing this will also prolong the life of your generator and maintain your fuel’s quality. Just remember that these storage principles apply whether you’re on the road or storing your RV for the offseason.

Only Use Approved Containers

Always store your fuel in containers specifically designed and approved for that fuel type. While containers will tell you which types of fuel they’re made for, it’s important to also take into account any safety standards set by your local or regional.

For gasoline and diesel, use durable, leak-proof containers with clear labeling. Avoid using generic containers that could be easily mistaken for water or other liquids. Propane tanks, on the other hand, must be certified and inspected periodically to ensure they remain in compliance with safety standards. Using approved containers minimizes the risk of leaks, spills, or vapor build-up, which is especially dangerous in enclosed areas.

Keep Fuel in the Proper Locations

Once you have the right container, think carefully about where you’ll store your fuel. Proximity, ventilation, and temperature control are critical factors. That’s why you should store fuel in areas that are dry, cool, and well-ventilated. Avoid storing it near heat sources, open flames, or electrical equipment that could create sparks.

For RV owners, this often means keeping fuel in a designated storage area intended for flammables. During the off-season, this could be a detached, secure location like a storage shed, but you’ll need a specialized storage compartment if you’re traveling with your extra fuel. Also, when you’re on the road, you must ensure your containers are secured to prevent tipping or rolling, which could lead to spills. On top of that, never store fuel inside the living quarters of your RV to avoid exposure to dangerous fumes.

When storing propane, always keep tanks upright and in a cool, shaded area, away from direct sunlight. Propane tanks should never be stored in confined spaces without proper ventilation, as they pose a risk of explosion in the unlikely case a leak occurs.

Safety Tips for Using Fuel

Of course, proper storage is only half the equation—safely using your fuel is equally important to protect both your equipment and yourself. Follow these guidelines whenever you’re handling or using fuel for your RV generator.

Ensure There Are No Leaks

Before using your stored fuel, check for any signs of leaking. Inspect the container or propane tank for cracks, dents, or corrosion that could lead to dangerous leaks. Fuel smells or visible puddles are obvious warning signs.

For propane tanks, a quick way to check for leaks is to rub some soapy water on the valve and connection points. If you notice the formation of bubbles, this is a sign of a potential leak, and you should repair or replace the tank immediately. Either way, regularly inspecting your storage setup ensures peace of mind and reduces the risk of accidents when transferring fuel to your generator.

Rotate Fuel Appropriately

Since fuel degrades over time, rotating your supply is a smart way to ensure safe and efficient usage. Gasoline and diesel, in particular, have limited shelf lives and may lose effectiveness with prolonged storage.

One way to rotate fuel is to use the oldest stock first before replenishing your supply with fresh fuel. Adding fuel stabilizers can extend the lifespan of gasoline and diesel, allowing you to store them for longer without compromising quality. For propane, ensure tanks are within their certification period, as outdated tanks pose unnecessary risks.

Don’t Overfill Your Generator

Overfilling your RV generator’s fuel tank is a common mistake that can lead to spills, vapor build-up, and even engine damage. Always refer to your generator’s manual to determine the appropriate amount of fuel to add.

Something else to note is when filling up, leave some room in the tank to allow for fuel expansion, especially in hot weather. This precaution prevents overflow and reduces the risk of fire or engine malfunctions. By following these simple fuel-handling practices, you can keep your generator running smoothly and ensure a safer experience overall.
