Why are Fuel Pump Part(s) Important

AKA: Fuel Transfer Pump, Fuel Delivery System (Actually refers to entire Fuel System)

The Fuel Pump supplies the force that moves your fuel from your gas tank to your engine’s combustion chamber. The process may start within the gas tank itself or at the engine block depending on the setup of your fuel system. Once in the combustion chamber, the fuel is mixed with air, compressed and exploded. The resulting force powers the internal movement of your vehicle’s engine.

Demystifying the fuel pump

You need a little background on how a fuel pump works before we get into the more advanced material. That means distinguishing the different types of fuel pumps, understanding the differences between OEM, premium and performance fuel pumps, diagnosing a faulty fuel pump or (more common) identifying a failing fuel pump accessory and—the graduate-level course—replacing a fuel pump.

Types of fuel pumps

The most basic distinction is the difference between an electric fuel pump and a mechanical fuel pump. Within that distinction there is further variation between the mechanical,  in-line and in-tank electric fuel pumps. If you have a electric unit, you may or may not need a complete fuel pump assembly with a hanger, strainer and sending unit. On the contrary, when you need a mechanical fuel pump, that's all you get—it is generally a self-contained unit. Fuel pump pressure and flow vary across of the spectrum of fuel pump options and applications.

Diagnosing a fuel pump

The next step is learning how to diagnose a faulty fuel pump. Symptoms of a failing fuel pump range from the obvious—the vehicle won't start because of low fuel pump pressure, to the subtle—you hear the fuel pump struggling. Regardless of fuel pump symptoms, the most common culprit behind a faulty fuel pump is a failed fuel pump accessory. Topping the list of common fuel pump accessory failures are a bad fuel pump relay and fuel pump regulator failure.

Fuel pump replacement

If you do work your way through the accessories and all signs point to a bad fuel pump, don't worry, replacing a bad inline or mechanical fuel pump can be a simple job for a seasoned DIYer. If you're a little green under the hood, a replacement fuel pump job is a great opportunity to push past your confront zone—it's the next logical step if you've mastered doing a tune-up or replacing your own brakes.
