What You'll Learn
The Onan installation guide recommends installing a filter before the fuel pump
To install a new fuel filter, you should first check your RV's manual for the exact part numbers needed for your specific Onan generator. The new fuel filter will fit inside the oval hole, allowing it to be connected to the fuel pump. It is important to take your time and only do this by hand to ensure the threads are straight and not crossed. Once the fuel filter is started, it can be tightened with a socket, but be careful not to overtighten.
It is also important to confirm your filter type before starting the process as the manual can sometimes be misleading. Additionally, it is recommended to check the fuel level before beginning any maintenance on your Onan generator. The fuel pick-up for the generator is usually located higher on the tank, so you need to ensure there is enough fuel in the tank to be above the generator pick-up line.
Replacing the fuel filter is a straightforward process, but it is imperative to perform regular maintenance on your Onan RV generator to keep it running smoothly. This includes changing the oil, performing a Seafoam treatment, and replacing the fuel filter when necessary.

Rust in the fuel can cause the pump to stop working
The Tiffin Allegro 35QBA is a Class A motorhome that runs on gas. Rust in the fuel can cause the fuel pump to stop working. This is because rust is considered a contaminant that can enter the fuel system and degrade the quality of the fuel.
Fuel contamination is a leading cause of fuel pump failure. Rust can enter the fuel system when the fuel filter is clogged or dirty, and the contaminants are no longer trapped. This blockage restricts fuel flow, and the pump has to work harder to push the fuel through the filter. Over time, the extra strain wears down the pump's components, leading to fuel pump failure.
The fuel pump should deliver fuel from the fuel tank to the engine at the appropriate pressure. When the pump is working harder than usual, it operates at a lower level of efficiency before complete failure. This can cause trouble starting the engine, and you may have to hold the ignition on for longer than normal. You may also notice weaker acceleration and worse fuel economy.
In addition, rusted fuel pump assemblies can affect the grounding of the fuel pump, causing it to be louder than usual. This can be due to the increased resistance in the circuit caused by corroded or rusted connectors.
To prevent fuel pump issues, it is recommended to periodically clean the fuel tank and replace fuel filters as per the manufacturer's guidelines.

The fuel filter is important for pump maintenance
The fuel filter is an important component of any engine, and its maintenance is crucial to ensure the smooth functioning of the fuel pump and the engine. The fuel filter is designed to remove impurities and debris from the fuel before it reaches the engine, and over time, it can become clogged with these contaminants. A clogged fuel filter can lead to reduced efficiency and even damage to the fuel pump and engine.
When the fuel filter is clogged, the fuel pump has to work harder to draw fuel through it, which can cause the pump to become less efficient and use more energy. This extra strain on the fuel pump can lead to increased wear and tear, reducing its lifespan and potentially causing it to fail prematurely. Therefore, it is important to keep the fuel filter clean and replace it at regular intervals to maintain the fuel pump in optimal condition.
Contaminated fuel can also cause damage to the engine. If debris bypasses the fuel filter and enters the fuel injector, it can clog the fuel passages and damage the injector, affecting the engine's performance and fuel efficiency. Rust in the fuel, for example, can be like small grains of sand, seizing the vanes of the pump and causing it to stop working. By regularly replacing the fuel filter, these impurities can be prevented from reaching the fuel injectors and causing damage.
The type of fuel filter used is also important. Different fuels may require specific types of filters, and using an incompatible filter can lead to problems. For example, E-85 fuel can cause issues with normal "paper" filters. Additionally, the micron rating of the filter, which relates to the size of particles it can block, should be considered to ensure effective filtration.
In summary, the fuel filter plays a critical role in maintaining the health of the fuel pump and engine. Regular replacement and proper selection of the fuel filter can help prevent clogging, reduce strain on the fuel pump, and avoid engine damage. By following the manufacturer's recommendations and choosing the right type of fuel filter, optimal performance and longevity of the fuel pump and engine can be achieved.
