Product Information
Fuel Filter. 
Restore the performance and reliability of your Porsche's fuel system with this Genuine Porsche Fuel Filter, manufactured to Porsche's original equipment specification and supplied under part number 311133511D. This precision-engineered fuel filter is designed to remove dirt, rust, and other contaminants from the fuel before it reaches the fuel pump, injectors, or carburettors, helping to protect critical fuel system components and maintain optimum engine performance.

Fits:
  • Porsche 914 (1970-1974)

Diagram Ref No 9

The fuel filter is an essential service component that ensures a clean and consistent fuel supply. Over time, contaminants accumulate within the filter element, restricting fuel flow and reducing filtration efficiency. A blocked or deteriorated fuel filter can affect engine performance, increase fuel system wear, and place additional strain on the fuel pump. Replacing the filter at the recommended service intervals helps maintain reliable fuel delivery and prolong the life of the entire fuel system.  

What This Product Does:
  • Removes dirt, rust, and contaminants from the fuel supply.
  • Protects the fuel pump, injectors, or carburettors from debris.
  • Maintains consistent fuel flow to the engine.
  • Supports optimum engine performance and efficiency.
  • Helps extend the service life of fuel system components.
  • Restores effective fuel filtration.
  • Delivers Genuine Porsche fit, quality, and reliability.

Symptoms Of Wear Or Failure:
  • Reduced engine performance.
  • Hesitation during acceleration.
  • Engine misfires or rough running.
  • Difficulty starting the engine.
  • Reduced fuel pressure.
  • Increased strain or noise from the fuel pump.
  • Restricted fuel flow caused by a blocked filter.
  • Age-related deterioration of the original component.

Why Replacement Matters:

  • The fuel filter plays a vital role in protecting your Porsche's fuel system by preventing contaminants from reaching sensitive engine components. A blocked or deteriorated filter can reduce fuel flow, impair engine performance, and accelerate wear of the fuel pump and fuel delivery system.
  • Replacing the fuel filter restores efficient fuel filtration, maintains consistent fuel delivery, and helps protect expensive fuel system components from contamination. As a Genuine Porsche replacement part, it provides the correct fit, filtration efficiency, and long-term durability required to preserve the performance, reliability, and originality of your Porsche.
