Collection: Fuel Pumps & Sending Units

Fuel pumps and sending units are essential components of a vehicle's fuel system. Here's a brief overview of each:

Fuel Pumps

Fuel pumps are responsible for delivering fuel from the tank to the engine. There are two main types:

• In-Tank Fuel Pumps: These are located inside the fuel tank and are commonly used in modern vehicles. They provide high-pressure fuel to the engine.
• In-Line Fuel Pumps: These are located outside the fuel tank but near it. They are typically used in older vehicles or certain types of engines that require low-pressure fuel.

Fuel Sending Units

Fuel sending units measure the amount of fuel in the tank and send this information to the fuel gauge on the dashboard. They consist of a float connected to a variable resistor, which changes resistance based on the fuel level. This information is then sent to the fuel gauge to display the correct fuel level.

Common Issues

• Fuel Pump Failure: Symptoms include difficulty starting the engine, sputtering, or the engine stalling.
• Sending Unit Malfunction: Symptoms include inaccurate fuel gauge readings or a fuel gauge that doesn't move at all.
