Usually, winter does not behave well with cars. There would always be several problems. However, starting problems are a common to deal with on cold days. Though a battery problem comes to mind at first when you cannot start your car, however, you will be surprised to learn about the unusual causes of struggle. It is frozen fuel line.

The fuel line is a hose that helps transport fuel from the tank to the engine. However, there are enough chances of fuel line becoming frozen in bone-chilling weather. In such a case, it is necessary to understand the frozen fuel line in detail.

What do you understand by “frozen fuel line”?

As it is clear, a fuel line should carry the fuel from the fuel tank towards the engine. Water in the form of vapour may occasionally enter the fuel line. And, in very cold temperatures, it may mix with the residual fuel in the line and freeze. If it happens, the fuel cannot reach the combustion chamber, and the engine would not be able to do anything without proper fuel supply.

However, most of the frozen substance is water itself, not the fuel. But when the cold weather turns the water into ice, fuel gets affected. However, it could be quite interesting to see how water or vapour enters the fuel line.

How do you identify a frozen fuel line?

Inspecting a frozen line physically is not feasible as the fuel line is hidden in the vehicle’s body. So how do you come to know about a frozen fuel line? These are a few signs that will definitely make you struggle with your vehicle and think about a remedy for a frozen fuel line.

1. Your car’s engine refuses to turn over

Without a drop of fuel (obstructed by frozen substances in the fuel line), how can you expect an engine to complete the combustion process? Eventually, it might refuse to turn over.

Sometimes the engine will start and you will not notice anything wrong until your car abruptly stops. This happens when fuel gets through the frozen fuel line to the engine. But it would be risky if your vehicle stops during a drive.

2. The engine just sputters inconsistently

If fuel is delivered partially due to the frozen fuel line (when the line is not blocked entirely), the engine might sputter without giving any warning.Though the frozen fuel line is a result of the presence of water, fuel does not freeze as easily.

When water can freeze at zero degrees Celsius (as is commonly believed), diesel struggles to survive at less than — 33 degrees Celsius, and petrol can lose its resistance at temperatures as low as — 40 degrees Celsius.

How can you get rid of a frozen fuel line?

Because the problem is more associated with cold weather, you can get rid of it by taking your vehicle to a warm place. A garage, on the other hand, is a good place, but it may take some time for things to warm up before you try to turn your car keys.

However, not all people have garage facilities, so you can try another hack. It is necessary to cover the bonnet with a cloth to retain heat and provide source of light over the hood. It may help in storing heat and making things normal.
