Your Fuel Transfer Pump Might Be Failing Because Of the Following Issues

Today, we have battery operated fuel transfer pumps that are faster and more efficient than the conventional gasoline transfer pumps. The modern battery operated pumps are very reliable. However, just like any other machine, sometimes, these pumps also stop working. Good news, the modern pumps are pretty easy to troubleshoot at home. We are going to cover some of the common fuel transfer pump issues that you can address on your own.

However, when the pump stops transferring fuel, don’t overlook following:

· The fuel tank is empty.

· The power to the pump is off.

· Check the fuse.

People usually replace the fuel when it starts blowing. However, if it blows continually, there is an electrical fault. Don’t replace the fuse. Inspect the pump and find the cause of the issue.

Following are the common gasoline transfer pump issues that are easy to troubleshoot:

Improper Installation

Sometimes, the pump does not transfer fuel due to some installation issues. Maybe, you missed something while installing the fuel transfer pump. Read the user manual and follow given instructions to install the pump properly. For example, the pump should be at the right height for efficient priming.


Following faults might cause the fuel transfer pump to stop working:

Motor Working but No Fuel Pumped

The motor is making humming sound but the fuel is not being pumped then there is a possibility of debris stuck in the rotor chamber. Usually, this happens due to the contaminated fuel.

No Suction and no Fuel Being Pumped

This usually happens when the bypass on the pump is blocked due to debris. The debris is present in the contaminated fuel. Make sure that there is a clean filter or strain fitted to the pump. Inspect the strainer and remove debris regularly.


This problem occurs when the pressure is too high. Apart from this, leaving the pump on by-pass for too long produces excess heat. This heat melts and deforms the seal.


Do not operate the pump for more than the recommended span of time.

Very Slow Transfer Rate

This occurs when the filters in the pump are blocked due to debris. Apart from this, clogged nozzles, tubes, or hoses can also cause slow transfer rate in the pump. Therefore, always inspect and clean the pump routinely.

Most of these faults and issues in the fuel transfer pump can be easily prevented. Therefore, inspect the pump routinely.
