Fuel Pumps, Parts & Fuel Tank Sender

What is a fuel pump?

Your vehicle's fuel pump delivers the right amount of fuel to the engine at the necessary pressure. There are both mechanical pumps, mostly found in older cars, and electric fuel pumps, which are mounted in the fuel tank.

Fuel Pump Symptoms

Faulty fuel pump symptoms include:

• Loud whining noise from the fuel tank.

• Sputtering engine.

• Difficulty starting the vehicle from lack of pressure.

A broken fuel pump can deliver too little or too much fuel, causing problems for your vehicle. If you need a fuel pump replacement, Halfords can help.

Fuel tank sender unit

The fuel tank sender unit ensures you can see how much fuel is available in your tank. By using a float and sensor mechanism, your fuel gauge will show a decrease in fuel as the float sinks.

If you have an issue with your fuel tank sender, this will be easy to notice based on when you fill up your car with fuel. You might notice that the fuel gauge is staying on 'full' constantly or it's reading as empty even though there is fuel in the tank. It is dangerous to drive with a faulty fuel tank sender unit as you won't know when you're about to run out of fuel.
