What To Know

  • Air bubbles in the fuel line can cause the pump to cavitate, which can lead to a loud banging noise.
  • A pump silencer is a device that can be installed on the fuel pump to reduce noise.
  • There are a few different things that can cause a diesel heater pump to be loud, including air in the fuel line, a dirty fuel filter, a worn pump, or a lack of a pump silencer.

Diesel heaters are a convenient and efficient way to stay warm during the cold winter months. However, the pump that circulates the fuel to the heater can sometimes be noisy. This can be a problem if you’re trying to sleep or relax in a quiet environment.

Causes of Diesel Heater Pump Noise

There are a few different things that can cause a diesel heater pump to be noisy.

  • Air in the fuel line: Air bubbles in the fuel line can cause the pump to cavitate, which can lead to a loud banging noise.
  • Dirty fuel filter: A dirty fuel filter can restrict the flow of fuel to the pump, which can also cause cavitation.
  • Worn pump: A worn pump may not be able to circulate the fuel properly, which can lead to noise.

How to Quiet a Diesel Heater Pump

There are a few different things you can do to quiet a diesel heater pump.

1. Check the Fuel Line for Air Leaks

The first thing you should do is check the fuel line for air leaks. Air leaks can allow air to enter the fuel line, which can cause the pump to cavitate. To check for air leaks, simply inspect the fuel line for any cracks or holes. If you find any leaks, you can repair them with a fuel line repair kit.

2. Replace the Fuel Filter

If the fuel filter is dirty, it can restrict the flow of fuel to the pump, which can also cause cavitation. To replace the fuel filter, simply locate the filter and unscrew it. Then, screw on a new filter and tighten it securely.

3. Inspect the Pump

If the fuel line and filter are in good condition, the next thing you should do is inspect the pump. A worn pump may not be able to circulate the fuel properly, which can lead to noise. To inspect the pump, simply remove the pump from the heater and inspect it for any signs of wear or damage. If the pump is worn, you can replace it with a new one.

4. Install a Pump Silencer

A pump silencer is a device that can be installed on the fuel pump to reduce noise. Pump silencers are typically made of rubber or foam, and they work by absorbing sound waves. To install a pump silencer, simply wrap it around the fuel pump and secure it with a zip tie.

5. Mount the Pump on a Vibration Isolator

A vibration isolator is a device that can be placed under the fuel pump to reduce vibration. Vibration can cause the pump to make noise, so by reducing vibration, you can also reduce noise. To install a vibration isolator, simply place it under the fuel pump and secure it with a bolt or screw.

6. Use a Quieter Fuel

Some fuels are quieter than others. If you’re having trouble quieting your diesel heater pump, you may want to try using a quieter fuel. Quieter fuels typically have a lower sulfur content, which can help to reduce noise.

7. Move the Pump to a Quieter Location

If all else fails, you may want to try moving the pump to a quieter location. This may not be possible in all cases, but it’s worth considering if you’re having trouble quieting the pump.

Troubleshooting

If you’ve tried all of the above and you’re still having trouble quieting your diesel heater pump, there may be a more serious problem. In this case, you should contact a qualified technician for assistance.
