What's a Fuel Pump?

A fuel pump is like the heart of a vehicle, usually located in the fuel tank. Like the heart pumpingblood to the rest of the body, a fuel pump pumps fuel from the fuel tank to the engine managementsystem. The engine management system then distributes the fuel to all of the cylinders located inthe engine. This is how most car's fuel pump functions.

However, the fuel pump in older cars (carburetor vehicles) works a little differently. It is located onthe engine. The fuel pump moves fuel from the fuel tank through steel lines and sends it to thecarburetor. The carburetor meters the fuel to the cylinders, whereas, newer cars use the fuelinjectors to do this.

Where is the Fuel Pump Located?

In most cars, the electric fuel pump is located in the back of the car, inside of the fuel tank.

In older(carburetor) cars, the mechanical fuel pump is located in front of the car, on the engine.

How to Maintain a Fuel Pump?

Using fuel injection cleaner and clean fuel will help the fuel pump work better. Also, changing thefuel filter every 24,000 miles will also help maintain the fuel pump (if it's replaceable).

What Causes the Fuel Pump to Fail?

1. Very low fuel level on a consistent basis

2. Clogged Fuel Filter

3. Fuel Pressure Regulator stops working
