Fuel System inspection, repair & replacement
The fuel system in a vehicle is responsible for storing, filtering, and delivering fuel to the engine. It consists of several components, including the fuel tank, fuel filter, fuel pump, fuel injectors, turbocharger and fuel pressure regulator.
A fuel tank stores fuel, which is passed through a filter to remove contaminants before reaching the engine. The fuel pressure regulator is responsible for maintaining fuel pressure and ensuring that the fuel injectors receive the correct amount of fuel at all times, regardless of engine load or speed.
Without a properly functioning fuel system, the engine performance will be impaired leading to poor fuel efficiency. In worse cases, the engine may not be able to run at all.
Fuel System services we offer
Inlet Manifold Gasket replacement
The inlet manifold gasket is critical to ensure that the air-to-fuel mixture is delivered to the engine cylinders correctly. Inlet manifold gasket replacement involves the process of removing the old gasket that seals the inlet manifold to the cylinder head and replacing it with a new one.
Throttle Body repair
The throttle body replacement process involves the inspection and replacement of the throttle body which is critical in regulating the airflow into the engine. This is so it can control the amount of air entering the engine based on the acceleration applied.
Fuel Pressure Regulator replacement
During a fuel pressure regulator replacement, the fuel system is depressurised before the fuel pressure regulator is removed and replaced with a new one. The fuel pressure regulator ensures the engine receives a consistent flow of fuel to the engine.
Fuel Filter change
During a fuel filter change, the mechanic will replace the fuel filter which is responsible for removing any debris or contaminants to ensure that only clean fuel is sent to the engine.
Fuel Injector repair
A fuel injector replacement involves inspecting the injector for clogging or leaks before replacing the part in order to restore its function of delivering the right amount of fuel to the engine.
Fuel Pump repair
A fuel pump replacement involves the inspection of the pump for damage, wear or clogging before replacing it with a new pump. Depending on the extent of damage, it may also require associated repairs such as fuel filter, injector or fuel pressure regulator replacement.
Mass Air Flow Sensor replacement
Mass air flow (MAF) sensor replacement involves removing the malfunctioning MAF sensor and replacing it with a new one so it can accurately measure the amount of air entering the engine and communicate this information to the engine control unit (ECU).
Throttle Position Sensor replacement
During a TPS or throttle position sensor replacement, the old sensor is removed and a new one is installed in its place so it can communicate the position of the throttle to the engine control unit (ECU).
Fuel Tank repair
Often a result of corrosion or cracks, the leaks in the fuel tank can reduce fuel capacity which can negatively affect the performance of the engine. Fuel tank replacement involves inspecting the fuel tank and then replacing it.
Turbocharger repair
The turbocharger increases the engine’s power output by compressing incoming air and over time this can become worn or damaged. During a turbocharger replacement process, the components are inspected for damage and replaced.

Frequently asked questions about fuel system inspection, repair & replacements
Read our answers to questions about fuel system inspection, repair & replacement costs, symptoms and more.
How much does it cost to repair a fuel line?
The cost to replace a fuel line can range between £80-£150. The exact cost will depend on which fuel line needs to be replaced, the make and model of the car and the location of the car.
Can you repair a fuel line?
It is possible to repair a fuel line in rare cases but should only ever be a temporary fix only. It is best to replace the entire fuel line not only to prevent damage in the future, it is also more cost-effective in the long run.
