Quantum replacement fuel pumps are designed for long-lasting performance and typically last over 2,500 hours or 100,000 miles. However, the lifespan of a fuel pump can depend on driving conditions, fuel quality, and maintenance habits. Proper upkeep—such as not letting your fuel tank drop below a quarter full—can extend its service life. Learn more about preventative fuel system maintenance on our blog.
There are several signs that indicate your fuel pump may be failing. These symptoms include: - Difficulty starting the vehicle - A loud whining sound when the engine is running - Surging or hesitation at constant speeds - A loss of power while accelerating If you notice any of these warning signs, it might be time for a fuel pump replacement.

A mechanical fuel pump is driven by the engine and is commonly found in older carbureted vehicles. In contrast, an electric fuel pump is powered by the vehicle’s electrical system and is more common in modern, fuel-injected vehicles. Electric fuel pumps generally offer higher fuel flow and pressure, making them ideal for applications that require a high pressure fuel pump or a fuel injection pump. If you're upgrading to a performance fuel pump, an electric fuel pump is typically the best choice for modern engines, especially those using fuel injection or E85 fuel.
Can I upgrade my stock fuel pump to a performance fuel pump? Yes, upgrading to a performance fuel pump is a great option if you're looking to enhance fuel flow for a modified or high-performance engine. But a high flow fuel pump could be overkill if you are not planning future performance upgrades such as adding a turbocharger or other power-adders.
The fluid you may find in your new Quantum fuel pump is testing fluid used during the manufacturing process to ensure the pump operates correctly under real-world conditions. We test pumps with fluid to check for proper flow, pressure, and functionality. This fluid is harmless and will not negatively affect your fuel system. It's completely safe to install and operate a pump that contains residual testing fluid.
