Peugeot Fuel Injectors

The five primary components are the fuel tank (stores fuel), fuel pump (pressurizes and delivers fuel), fuel filter (removes contaminants), fuel injectors (spray atomized fuel into cylinders), and fuel pressure regulator (maintains correct system pressure). Peugeot THP and BlueHDi engines also include high-pressure fuel pumps and rail systems for direct injection technology.

Fuel pump replacement for Peugeot models typically costs between R3,500-R8,500 in South Africa, depending on the model and engine type. Parts alone range from R2,000-R5,500, with labour adding R1,500-R3,000. BlueHDi high-pressure fuel pumps are more expensive, often exceeding R12,000 for parts due to their complex engineering.

Common symptoms include difficulty starting, engine sputtering or stalling, loss of power especially when climbing hills on SA roads, unusually high or low fuel consumption, and the check engine light appearing. You may also notice the engine running roughly at idle or hesitating when accelerating from traffic lights, particularly in Peugeot 208 or 2008 models with THP engines.

Peugeot recommends fuel filter replacement every 30,000-40,000 km for diesel models (DV6, BlueHDi) and 60,000 km for petrol engines. In South African conditions with variable fuel quality, changing diesel filters every 20,000-30,000 km is advisable to prevent injector damage. Fuel filters cost between R250-R850 depending on the model.

Yes, contaminated or low-quality fuel can cause serious damage to Peugeot engines, especially modern turbocharged units. Water or sediment in fuel can corrode injectors (R1,500-R3,500 each), damage the high-pressure fuel pump (R12,000+), and cause carbon buildup on valves. Always use reputable fuel stations and consider using fuel system cleaners every 10,000 km to maintain optimal performance.
