Just like blood in the human body, fuel is indispensable to your vehicle's operation. While the body has a heart to pump blood throughout the body, your car has something similar: the fuel pump. It draws out fuel from the fuel tank. Fuel is then ignited in the combustion chamber so that the engine starts generating power needed for your car to run. The fuel pump, however, can't do anything on its own. It comes with a few other components. All these make up the fuel pump assembly.
The centerpiece of this assembly is the pump. The fuel pump comes in two types: the mechanical pump and the electric pump. The mechanical pump is usually positioned in the engine block or head, and most carbureted engines use it. In this car fuel pump assembly, the engine has an extra lobe that operates a lever in the pump to increase the engine's volume. This is how fuel is drawn from the gas tank. Eventually, fuel is squeezed through its port and reaches the bowl of the carburetor. Gravity has a lot to do with how fuel is transported through a mechanical pump. An electric pump, on the other hand, uses the principles of positive fuel lines. Because of positive pressure, fuel is forced through the fuel injection system before being fed to the engine. Most modern vehicles use the electric pump because it's lightweight and more efficient, not to mention most vehicles nowadays have fuel-injected systems. Unlike the mechanical pump, the electric pump is installed inside the gas tank. This way, it's less likely to be accidentally ignited.
Nowadays, fuel pump assemblies contain not only the fuel pump but other components as well. These components include the fuel sender, float, strainer, and a set of wiring harnesses. Top-caliber aftermarket parts also come with a service manual that tells you everything you need to know about the entire assembly. This makes installation or replacement manageable for all car owners.
The fuel pump is exposed to damaging elements that can eventually damage its small components. When this happens, the fuel pump's performance will surely go south. Although you can ask your repair guy to fix the problem, it's better if you replace the entire fuel pump assembly.
With brand-new components all in mint condition, you can be sure that the fuel pump won't fail any time soon. A broken fuel pump is not something you can ignore. If you want no trouble with engine hesitation, rough acceleration, poor fuel economy, and harmful emissions, then take time to fix the problem. Install a new fuel pump assembly that can guarantee the smooth and efficient performance from your fuel system and your engine. The best aftermarket options can be found online.
