If engine oil is the lifeline of your engine, then fuel is its source of food. In applications such as gas- or diesel-powered on-road vehicles, a fuel pump is tasked with delivering fuel in liquid form from a fuel tank to the engine, where it can be burned in combination with air as a source of energy, ultimately powering your vehicle.
Since the ’70s, most modern cars use an electric-style fuel pump located inside your vehicle’s fuel tank. When compared to mechanical fuel pumps of the past, these electric fuel pumps feature several key benefits. For starters, an electric fuel pump can be mounted almost anywhere (including outside of the fuel tank in racing applications); they’re also more reliable, and provide increased longevity.
Whether you’re looking to replace an aging fuel pump or simply interested in upgrading your existing electric fuel pump, there are plenty of options out there. However, it’s worth noting that electric fuel pumps are typically not universal, and each vehicle has its own specific needs, such as flow rate and pressure, so always be sure to double-check that you’re selecting the correct part for your make and model. To help you out, we’ve partnered with Advance Auto Parts to bring you this list of five top electric fuel pump brands.

Delphi Electric Fuel Pump
Another big name in OEM replacement parts is Delphi, and the company’s electric fuel pumps are built to OEM standards, and designed to operate in some of the harshest conditions to provide extreme durability. If you live in a hot climate, such as California or Arizona, or a cold one like Minnesota or Illinois, you might want to consider this offering.
Delphi’s electric fuel pumps are designed to operate in extreme temperatures, provide quick engine starts, and avoid low-fuel hesitation in gasoline and alcohol-based fuel applications. Another aspect that sets this Delphi unit apart is its low-amperage drawing characteristics, which puts less load on your vehicle’s electrical system.

Bosch Turbine Electric Fuel Pump
You’ve probably noticed a trend here of choosing some of the “big players” in the OEM replacement parts business, and another one on our list is Bosch, a company often referred to as the “gold standard” in fuel components. Bosch’s Turbine electric fuel pump certainly meets that criteria, as it features some of the leading advantages in fuel pump technology.
What makes Bosch’s Turbine fuel pump different is its design; as a result, this electric fuel pump offers a near-silent operation which not only improves drivability, but also helps reduce wear, delivering a much longer service life. Bosch also integrated a non-return valve, which maintains system pressure long after your vehicle has been shut off, which in turn prevents hot-start problems. All in all, Bosch’s Turbine electric fuel pump is a great option for replacing a worn, tired, or failed OEM fuel pump.

Denso’s electric fuel pumps feature an OEM-like construction and come backed by a one-year warranty.
In addition, Denso subjects all its electric fuel pumps to a rigorous testing and inspection process to ensure every electric fuel pump that leaves its facility meets the company’s high standards, making them a reliable solution for any driver looking for an aftermarket replacement.

What are the signs of a failing fuel pump?
Fuel pumps can be quite finicky and sometimes hard to diagnose. We always recommend taking your vehicle to a professional repair shop to confirm a failing fuel pump through troubleshooting, but here are a few common symptoms of a fuel pump on its way out:
- Decreased fuel pressure
- Engine sputtering at high speeds
- Loss of power when your vehicle is under load
- Decreased fuel economy
- Trouble starting your vehicle due to lack of fuel pressure
Again, these are only some of the symptoms of a worn or failing fuel pump — your mileage may very (no pun intended).
How do fuel pumps wear out or fail?
Just like any other part on your car, over time your fuel pump will eventually wear out. Although OEM fuel pumps are typically designed to last the lifespan of the car, many factors come into play that can shorten the life of your vehicle’s fuel pump. The quality of fuel you fill up your car with, how often you fill up, and even how often you let your tank go down past 1/4 full all play a role in how long your factory fuel pump will last.
To help ensure fuel pump longevity, it’s recommended to not let your fuel tank fall below 1/4 full — this is because fuel is used to help lubricate the fuel pump in the tank.
Should I have my fuel pump rebuilt or replaced?
We always tend to recommend replacing your worn or failed fuel pump over refurbishing it. This is because the guarantee for new parts is far superior to a refurbished unit. A new fuel pump is built with all-new components, which results in a much more reliable, much longer-lasting solution when compared to a rebuilt one. In addition, the cost of refurbishing a fuel pump typically isn’t worth it when compared to the cost of a replacement unit.
