A fuel pump assembly is one of many vital components necessary to keep your engine functioning properly. It's not hard to figure out that this vital mechanism pumps fuel from your tank to your engine, and that if it stops working so then does your car. A poorly working pump often shows up more subtly than that though, so you'll want to know what to look for to gauge whether something's wrong. If your pump assembly doesn't function properly, you'll feel the lag in your car's performance, particularly when you try to accelerate. It's of the utmost importance to catch a damaged fuel pump assembly early on, because if it's damaged or malfunctioning it can cause lasting damage to multiple engine systems unless you make the effort to replace it immediately. Not that it takes much effort if you buy a new part from BuyAutoParts.com.
Fuel Pump Assembly - General Overview
The primary job of the fuel pump is to deliver fuel from the gas tank to your car's engine. Most modern cars use a fuel pump located in the gas tank, while some older models have the fuel pump outside the tank. There are two different kinds of fuel pumps: mechanical and electric.
Mechanical fuel pump - as the name implies, this type of fuel pump uses mechanical motion to produce the necessary hydraulic thrust to get fuel from the gas tank to the engine. The primary catalyst for the mechanical fuel pump is a camshaft, which turns to create a lifting motion from an actuating lever. A suction force created by an inner diaphragm sends the fuel through the mechanical fuel pump's one way valve. Another one way valve forces the fuel toward the carburetor. Even though the mechanical fuel pump may produce a significant fuel flow, the carburetor takes only the amount of fuel necessary for normal engine operation.
Electrical fuel pump - very similar to the mechanical fuel pump is scope, the electrical fuel pump differs in one significant way: it has a solenoid switch as the main catalyst, as opposed to the camshaft. From there, the general action is very similar. The electrical fuel pump uses the same type of diaphragm, one way valves and control mechanisms to deliver fuel from the gas tank to the carburetor.

Eventually, your car's fuel pump will fail. Initial quality, driving style, maintenance and other factors will determine how long your fuel pump assembly will ultimately last. In order to keep your car driving like the day it rolled off the assembly line, you may have to replace the fuel pump assembly - either with the help of your local mechanic or with a money-saving DIY project, which is quickly becoming a much more popular method of car repair, especially for savvy and smart automobile owners.
Is your fuel pump near the end of the line? Are there certain signs & symptoms that definitively determine if the fuel pump is failing? While not everything is 100% fool-proof, a defined set of performance glitches and other warning signals can indicate fuel pump failure.
It's a simple fact: if your fuel pump starts working, your car will stop. Without a constant source of fuel delivery to the engine, you'll stall out. Many people associate a sputtering engine as something wrong with the spark plugs, distributor cap or spark plug wires. While that's a pretty good educated guess, a bad fuel pump provides many of the same symptoms.
Some of the typical signs of a failing fuel pump include:
- Fluctuating temperature. If the fuel pump isn't working properly, the car's core temperature may go up and down. Whenever the fuel pump motor goes bad, the car temperature fluctuates drastically. Thus, a bad fuel pump assembly is often misdiagnosed as radiator problems, low coolant level and other related issues.
- Bad gas mileage. The fuel pump's relief valve limits how much fuel is used by the fuel pump. If the relief valve isn't working, more fuel than necessary will enter the engine. This wasted fuel will start to show up in your mileage calculations. This is just one more reason why you should check your gas mileage at regular intervals.
- Sputtering sound coming from engine.
- Loss of power at high speeds.
- A clicking sound from fuel pump.
- No power upon acceleration.
- Power drain when turning, going up hills, coming out of a red light, etc.
- Sudden and unexplained power surges.
- Car has trouble starting. While the starter is usually targeted as the culprit, improper fuel delivery is a major reason why cars can't start. A bad fuel pump in the winter time is even more troublesome, because the cold temperatures can compound an already weakened fuel delivery system.
There are many reasons why fuel pumps fail. General wear and tear are two big reasons, but the fuel pump's design, function and unique relation to other components (like the fuel tank) are also important. Your fuel tank can stop working because:
- Bad driving conditions. If your fuel tank is subject to excessive moisture (in the form of rain, snow, sleet, etc.), the tank's structural integrity can impact the fuel pump. A rusted out fuel tank is a big factor why fuel pumps ultimately fail.
- Chronic low fuel level. This might be the biggest reason why fuel pumps fail.
- Bad electrical connections. For newer model cars that have an electrical fuel pump, a corroded connection, kinked wire or other issue can cause the fuel pump to deliver fuel from the tank to the engine very slowly, or not at all.
- Dirty fuel. Bad fuel is hard to pinpoint, but many auto experts target the occasional bad batch of fuel as a reason that fuel pumps stop running. In order to prevent this, it is recommended that you always use the best quality fuel (think Sunoco, Shell, BP and other well-known fuel brands).
Keeping the Fuel Pump Running Properly
As far as fuel pump assembly maintenance is concerned, it's pretty simple to give your fuel pump the best chance for an extended life. Actually, it's about as easy as you can get, in relation to other maintenance protocols. It might be the best-kept secret if the complete annals of car maintenance. So what's the best way to take care of your fuel pump assembly? Keep your gas tank level properly maintained.
It sounds easy, but unfortunately many people choose to run their cars with the fuel warning light on. It is not recommended to operate your car this way. This style of driving provides unnecessary stress and strain on the fuel pump. This concept applies to other car systems which draw fluid from a reservoir. In your brake system, chronically low levels of brake fluid will negatively affect overall brake performance. That same principle applies to the gas tank. Think of your gas tank as a fluid reservoir, and the fuel pump as a straw. Whenever the level gets too low, the force necessary to draw fuel out of the tank greatly increases. If you drive too often in this manner, it's only a matter of time before the fuel pump wears out.
Other tips for getting the most out of your fuel pump:
- Always keep at least a half tank of gas in your car. Forget the fuel warning light - your warning light should be anything less than half full.
- If you don't use a tank of gas in a month, add a fuel cleaner to your gas tank.
- For out of tank fuel pumps, inspect (and replace, if necessary) every 25,000 miles. Because of the location of these type of pumps, they're subject to certain stresses their inside the tank counterparts never experience.
- Beware of pumping fuel at gas stations that are getting refilled from tanker trucks. Generally speaking, there is more dirt and foreign substances during these refueling periods.
