If you’re having trouble with your car’s engine, there are many possible causes. One of the most common is a faulty fuel pump. There are many different types of fuel pumps, though, so it’s important to know what type you have before replacing it.
Mechanical fuel pump
A mechanical fuel pump is a mechanical device that draws fuel from the fuel tank and forces it into the engine’s intake manifold. The pump is driven by a crankshaft or a camshaft and can be an integral part of the engine or separate, as in most modern vehicles.
In either case, it cannot be removed without taking apart several other critical components of your vehicle (which isn’t something you want to do unless necessary).
Electrical fuel pump
While the gasoline engine runs, an electric fuel pump draws fuel from the tank and pumps it to the engine. The main difference between a mechanical and an electric pump is that one uses a battery to power its operation while the other uses mechanical means to generate force.
The primary benefit of using an electric pump over a mechanical one is that there’s no need for a separate relay box or wiring harness to connect it; most vehicles already have relays built into their electrical systems.
This makes installation much simpler and cheaper than installing both types separately because you won’t need additional parts or labour costs for installation. Additionally, many aftermarket accessories, such as lift kits. Require additional power sources like batteries so this option can save you money on additional parts!
However, installing an aftermarket accessory can be tricky if your vehicle doesn’t have these features unless you have access to specialized tools like multimeters. That allow users to detect voltage fluctuations caused by faulty components like relays.
In-tank fuel pump
An in-tank fuel pump is a device that is installed inside the fuel tank itself. The pump is usually mounted to the bottom of the fuel tank, and it draws fuel from there and sends it through a hose connected to an electrical connector on your engine. The function of this type of pump is to keep your vehicle’s gas tank full of liquid gasoline at all times. So that you can be confident that your vehicle will start when you need it most. In-tank pumps are standard on older cars and motorcycles but are being phased out in newer models. Thanks to their bulkiness and occasional tendency to leak slightly over time due to wear or damage.
In-line fuel pump
In-line fuel pumps are the most common style of the electric fuel pump. An in-line fuel pump is located inside the fuel tank and is connected to the fuel line, filter, and injectors.
An in-line electric fuel pump has a pressure regulator that controls how much pressure goes into your engine. The regulator also keeps it from exploding if there’s too much pressure from a leak or other problem.
This article covered different types of fuel pumps and how they work. Starting with a brief history of electric pumps and then explaining how they operate. You also looked at mechanical pumps used in many cars today and in some older vehicles. Electric pumps are more efficient than their counterparts but require some maintenance. Whereas mechanical ones do not need any upkeep at all.
