The fuel pump is a key component of the fuel system in lorries. Its task is to supply the engine with the right amount of fuel. If this component fails, the vehicle may not function properly or may even refuse to start at all.

Symptoms indicating a fuel pump malfunction

The first symptom indicating a potential fuel pump malfunction may be a drop in engine power. If you notice that your lorry has suddenly stopped accelerating as it should, it is worth checking the pump. A drop in power can also be the result of other problems, but it is worth ruling out fuel pump failure as one of the possible causes. Another warning sign is irregular engine operation. If you notice that the engine is running unevenly while driving, it may mean that the fuel pump is not supplying enough fuel. In this case, it is worth visiting a TIR service centre, where specialists will diagnose the vehicle and check whether the pump is working properly. Another symptom that may indicate a fuel pump failure is difficulty starting the engine. If you notice that your lorry has trouble starting, especially when the engine is cold, this may be due to the pump malfunctioning.

What to do in case of a fuel pump failure?

If you suspect a fuel pump failure in your lorry, it is best to visit a professional lorry service centre. There, specialists will carry out a detailed diagnosis of the vehicle and confirm or rule out a fuel pump failure. If the fault is confirmed, the damaged component will need to be replaced with a new one. It is worth remembering that a fuel pump is a component that is subject to wear and tear. Therefore, it is advisable to service your vehicle regularly and check the condition of the pump. This way, you can avoid unexpected breakdowns and keep your lorry in good working order.
