Fuel pumps normally produce a low humming sound, but excessive noise may indicate wear or mechanical issues. Common causes include cavitation, clogged filters, or motor strain due to low fuel levels.
Addressing noise early is important, as it can prevent more serious failures such as motor burnout or pressure inconsistencies. Routine inspection and maintenance are the best ways to mitigate noise-related problems.
A quieter, well-functioning pump also improves the customer experience, giving a perception of quality and reliability in station operations.
