Both carbureted and fuel-injected engines require the use of a fuel pump to get fuel into the combustion chamber. They each use a different kind of pump, though. Carbureted engines use a mechanical pump while fuel-injected engines use an electric pump. In both cases, the pump will eventually fail and will have to be replaced.
Read on to find out how to get the right fuel pump for your car.
What's the job of the fuel pump?
The main purpose of the fuel pump is to make sure that fuel is delivered from the gas tank to the engine's combustion chambers.
In a carbureted engine, the carburetor creates a vacuum that draws the fuel-air mixture into the engine. This same vacuum draws fuel from the tank and into the engine's cylinders. Since this vacuum is not always enough, a mechanical pump driven by the engine helps bring fuel from the tank to the engine.
In an electronically fuel-injected engine, an electric pump sits by the fuel tank. It is controlled by the engine's computer and carefully pumps out a specified amount of fuel from the tank to the engine.
How to know if your fuel pump is going bad?
There are several signs that could mean that your fuel pump is going bad, but the biggest one is when the engine dies and fails to restart. Basically, the car will act as if it has no fuel even if its gas tank is still filled.
Other signs include losing power when pulling away from a standing stop, losing power when the engine is under high strain, and a misfiring engine.
What to look for in a new fuel pump?
One of the first things you have to check is whether the pump is mechanical or electric. You probably know what type of engine your car has, so you also know what kind of pump it uses.
We suggest that you check the specifications of the fuel pump that your vehicle uses to make sure you can get one that completely matches them.
Of course, there's also the matter of size. The right fuel pump must perfectly fit once it is installed in your vehicle.
We recommend that you get only products from established brands. This way, you can ensure the quality and reliability of the product. Read reviews to find out which fuel pump is the best, compare prices, and get the one that will give you the most bang for your buck.
