Over time, the fuel pump and fuel line can experience wear and tear, affecting their performance and requiring maintenance or replacement. It is essential to monitor their condition and keep them free from debris, clogs, or leaks. Proper maintenance ensures the generator receives an uninterrupted fuel supply, preventing performance issues or unexpected breakdowns.
To maintain the fuel pump and fuel line, regular inspections and cleanings are necessary. It is advisable to refer to the generator's manual for specific maintenance guidelines. However, some general practices include periodically checking for debris or clogs, especially if the generator is stored with fuel for extended periods. Additionally, using fuel stabilizers can help maintain fuel quality and prevent clogging in the fuel line and other engine components.
In conclusion, the generator's fuel pump and fuel line are critical components that require proper care and maintenance. By understanding their functions and implementing regular maintenance routines, you can ensure the generator's reliable performance and extend the lifespan of these essential parts.

Leaving the tank empty vs full
Leaving the generator's fuel tank empty can be beneficial to prevent fuel wastage and ensure the generator is always ready for use. By emptying the tank, you reduce the risk of fuel degradation, especially if the generator is stored for extended periods. Old gasoline can go bad, clog the fuel line, and cause starting problems, making it essential to drain the tank before storing the generator. Additionally, emptying the tank reduces the risk of fuel leakage, which could create a hazardous situation.
On the other hand, some motorhome owners prefer to leave the generator's fuel tank full or partially full. One reason for this is to ensure that the generator has enough fuel to run for extended periods without refuelling. This is especially important for those who frequently use their generators or experience power outages. By keeping the tank full, they can avoid the inconvenience of refuelling during extended use. Additionally, some people believe that a full tank can help maintain the generator's performance by keeping the float needle seat from sticking and preventing crud from forming in the tank.
Those who opt to leave the tank full often use fuel stabilizers to prevent fuel degradation and maintain fuel quality. Fuel stabilizers can extend the lifespan of the fuel, allowing it to be stored for longer periods without concern for fuel deterioration. However, it is crucial to use the correct type and amount of stabilizer and to ensure proper storage conditions to avoid issues with the generator.
Ultimately, the decision to leave the generator's fuel tank empty or full depends on various factors, including usage patterns, storage conditions, and personal preferences. Both approaches have their advantages and considerations, and motorhome owners should weigh these factors to determine the best course of action for their specific situation.
To make an informed decision, it is recommended to refer to the generator's manual, consult with experienced motorhome owners, and consider the local climate and storage conditions. By understanding the benefits and potential drawbacks of each approach, motorhome owners can make a well-informed choice to ensure their generator is ready and reliable when needed.

Fuel stabilizers
Generators are often stored with fuel inside the tank, which can cause issues when the generator is not used for a long time. The fuel can degrade and gum up the carburetor, causing the generator to fail to start. This is where fuel stabilizers come in.
There are several fuel stabilizers available on the market, such as Sta-Bil 360, Stabil Marine 360, and PRI-G. These products can be purchased from automotive stores, hardware stores, or online retailers like Amazon. The recommended ratio for most stabilizers is approximately 1 ounce of stabilizer per 2.5 gallons of fuel, but it is important to follow the instructions on the specific product.
Some people choose to store their generators with a full tank of fuel and a stabilizer, while others prefer to run their generators dry and only add stabilizer when necessary. It is recommended to change the fuel in the tank after one year, even with a stabilizer, to ensure optimal performance.
By using a fuel stabilizer, you can have peace of mind that your generator will start up when you need it most, even after being idle for a long period. It is a simple and effective way to maintain the health of your generator and ensure it has a long lifespan.
