The Differences Between Mechanical And Electrical Fuel Pumps

The Differences Between Mechanical And Electrical Fuel Pumps

Your vehicle’s fuel pump has to crucial role to deliver fuel to your car’s engine. As you know, your engine requires a working spark plug, compression, and adequate fuel to run smoothly. The modern car has two fuel pumps, a mechanical and an electrical one.

Mechanical Fuel Pumps – Installed on top of the engine and are driven using the camshaft. Mechanical fuel pumps use a type of vacuum to deliver the fuel to the engine. If you drive a specialty car or a carbureted vehicle, you will find that it has a mechanical fuel pump.

Electrical Fuel Pumps – It has injectors, which squirt fuel into the engine’s combustion chambers. Controlling the fuel pump is a computer system and its role is to monitor the air and fuel ratio, the throttle’s position, and the content of the exhaust. It is found inside or near the fuel tank and doesn’t use a vacuum to deliver the fuel to the engine.

If your vehicle has a mechanical fuel pump, chances of it failing are more than if your car had an electrical fuel pump. In the event the electrical fuel pump malfunctions, it creates a lot of trouble for the driver. For instance, it can affect the engine, causing it sputter and die or the engine cranks, but refuses to start and run.

To help you increase the lifespan of your car’s mechanical and electrical fuel pumps, here is what we want you to do:

  • Change your inline fuel filter on a yearly basis or after every 12,000 to 15,000 miles
  • Clean your fuel system regularly by visiting us to have your car’s fuel injection system and throttle body cleaned after every 20,0000 to 30,000 miles
  • Do not allow the fuel level to fall below 1/4

If your vehicle does malfunction and you do not know what the problem is, you can always visit us. We will inspect your vehicle to root out the problem.
