How Do I Protect My Fuel Pump?

It is necessary to protect your Fuel Pump for the health of the whole fuel mechanism and to keep it running for as long as possible. Most Fuel Pumps are made to have a life of 100,000 to 150,000 miles but can wear out prematurely if not taken care of properly. The simplest method to protect a Fuel Pump is by keeping your fuel tank at least a quarter full. The fuel inside the tank cools the pump, and if the tank is always run too low, then the pump is at risk of overheating-and a hot pump is an inefficient pump that won’t last very long.

Another key method of safeguarding your Fuel Pump is through periodic replacement of the fuel filter. A fuel filter that reaches a clogged state requires the pump to work harder in an attempt to push fuel through the system, and this leads to early wear. Most manufacturers recommend changing the fuel filter at an interval of 30,000 miles, but this may vary depending on the type of vehicle and operating conditions. The pump may also be damaged by grimy or contaminated fuel. Using high-quality fuel from a reputable source reduces contamination possibilities that could block the system and cause stress on the pump.

In 2019, Toyota had to recall over 700,000 vehicles because of fuel pump failures; the reason for those failures was contaminated fuel. This once again underlines the importance of clean fuel and timely changes of fuel filters.

The other very critical area to maintain for the protection of the Fuel Pump is proper fuel pressure. High-performance engines demand fuel systems that can maintain constant pressure under load, and this normally ranges from 40 to 60 PSI for a standard engine. If fuel pressure is below or above specifications, the pump may fail prematurely. A fuel pressure regulator can be installed to ensure the system stays within the correct range, especially for modified or high-performance vehicles.

As it was pointed out by one of the most prominent automotive names, David Vizard, “Preventative maintenance is key to avoiding costly repairs.” Regular check-ups of your fuel system, keeping fuel levels up, and ensuring clean fuel will help you get the most out of your Fuel Pump.
