Understanding the Onan 4000 Fuel Pump

The Onan 4000 fuel pump is responsible for delivering fuel from the tank to the generator’s engine. It is designed specifically for use with Onan generators and is an essential component for proper functioning of the generator.

Factors to Consider

When shopping for a new fuel pump for your Onan 4000, there are several factors that you should keep in mind:

  • Type of Fuel: The Onan 4000 fuel pump is available in two types: gasoline and diesel. Make sure you select the appropriate type based on your generator’s fuel requirements.
  • Brand: While there are many aftermarket options available, it is always recommended to stick with genuine or OEM (original equipment manufacturer) parts from trusted brands like Cummins/Onan. This will ensure quality and reliability.
  • Budget: Set a budget for yourself before starting your search. While it may be tempting to choose a cheaper option, keep in mind that a high-quality fuel pump will last longer and save you money in the long run.
