My Buying Guide on Onan 5500 Generator Fuel Pump

When I decided to invest in an Onan 5500 generator, I quickly realized that having a reliable fuel pump was just as important as the generator itself. The fuel pump is crucial for ensuring that the generator operates efficiently and effectively. Here’s a guide based on my experience to help you choose the right fuel pump for your Onan 5500 generator.

Understanding the Importance of a Fuel Pump

In my experience, the fuel pump is essential for delivering fuel from the tank to the engine. A malfunctioning fuel pump can lead to poor performance or even failure to start. I learned the hard way that regular maintenance and timely replacements can save me from costly repairs and downtime.

Types of Fuel Pumps

When I started my search, I discovered that there are generally two types of fuel pumps for the Onan 5500 generator: mechanical and electric.

  • Mechanical Pumps: These pumps are typically more durable and reliable. I appreciated that they are often less expensive and simpler to install.
  • Electric Pumps: While these can provide better fuel flow, I found them to be more complex and sometimes prone to electrical issues.

Choosing the right type depends on my generator’s specific needs and my comfort with installation.

Key Features to Look For

From my experience, I recommend considering the following features when purchasing a fuel pump:

  • Compatibility: Ensure the pump is designed specifically for the Onan 5500 generator. I found that using compatible parts significantly improved performance.
  • Flow Rate: Look for a pump with an adequate flow rate for your generator’s requirements. A higher flow rate can improve efficiency and performance.
  • Durability: I sought pumps made from high-quality materials that could withstand various conditions. It’s worth investing in a pump that will last.
  • Warranty: A good warranty can provide peace of mind. I always check for a warranty that covers parts and labor.

Where to Buy

I found several reliable sources for purchasing an Onan 5500 generator fuel pump. Here are my recommendations:

  • Authorized Dealers: Buying from authorized dealers ensures that you receive genuine parts. I felt more secure knowing my pump was specifically designed for my generator.
  • Online Retailers: Websites like Amazon and eBay often have competitive prices. Just make sure to read customer reviews to gauge the reliability of the seller.
  • Local Auto Parts Stores: Sometimes, I was able to find what I needed locally, which saved on shipping time.

Installation Tips

Once I had my fuel pump, I followed these tips for installation:

  1. Read the Manual: I always refer to the generator’s manual for specific instructions.
  2. Gather Tools: Having the right tools on hand made the installation process smoother.
  3. Take Safety Precautions: I made sure to disconnect the battery and work in a well-ventilated area to avoid any potential hazards.
  4. Test the Pump: After installation, I always test the pump before using the generator to ensure everything is functioning properly.

Maintenance and Care

To prolong the life of my fuel pump, I established a regular maintenance routine. This includes:

  • Regular Inspections: I check for leaks and clogs periodically.
  • Fuel Quality: Using high-quality fuel helped reduce the risk of debris clogging the pump.
  • Cleaning: Occasionally, I clean the fuel filter to keep the system running smoothly.

Investing in a high-quality fuel pump for my Onan 5500 generator was a game changer. I realized that taking the time to choose the right pump and maintaining it properly can lead to years of reliable service. I hope my buying guide helps you make an informed decision when looking for your own Onan 5500 generator fuel pump!
