Understanding the Importance of a Fuel Pump

When I first began my journey with Onan generators, I quickly learned that the fuel pump plays a crucial role in ensuring the engine runs smoothly. It’s responsible for delivering fuel from the tank to the engine, and any malfunction can lead to performance issues or even complete failure to start. Having a reliable fuel pump is essential for maintaining the generator’s efficiency and longevity.

Types of Fuel Pumps

During my research, I discovered that there are different types of fuel pumps available for Onan generators. The most common types include mechanical and electric fuel pumps.
