About the Porsche Cayman S Fuel Pump
The Porsche Cayman S is the high performance variant of Porsche's mid engine sports coupe, launched in 2005 as a coupe sibling to the Boxster roadster. The 2005 Cayman S used the M97/21 3.4 liter naturally aspirated flat six engine producing 295 hp, paired with either a 6 speed manual or Tiptronic S automatic transmission. The fuel pump on the Cayman S is an electric submersible unit located inside the fuel tank. It pulls gasoline from the tank reservoir and delivers it under controlled pressure (3 to 5 bar) to the fuel rail at the engine. The pump runs continuously while the engine is running and is typically activated for a few seconds when the ignition is turned on to pre pressurize the fuel system for clean starts.
Our used OEM Porsche Cayman S fuel pump comes from a 2005 donor vehicle. Built with high grade metal and composite components for long service life, the pump is rated for 200 to 250 liters per hour flow rate at 3 to 5 bar pressure, 12V system compatible. We verify pump pressure, flow rate, and electrical continuity before shipping.

Can I install this fuel pump myself?
The pump is designed for a direct bolt on installation; however, professional installation is recommended for optimal results.
How does the fuel pump affect engine performance?
A properly functioning fuel pump ensures consistent fuel delivery, which is critical for efficient combustion and overall engine performance.
What signs indicate a failing fuel pump?
Symptoms include engine misfires, poor throttle response, and reduced fuel efficiency. If you notice these, it may be time to replace your fuel pump.
Will this fuel pump improve my fuel economy?
While optimal fuel delivery can enhance engine efficiency, overall fuel economy depends on several factors, including driving habits and maintenance.
What maintenance does the fuel pump require?
Regular inspections and proper fuel system maintenance will help ensure the longevity and consistent performance of the fuel pump.
Will this fit my Cayman without the S badge or my Boxster S?
The base 2.7L Cayman and 3.4L Cayman S used different pump specifications. The Boxster S of the same era (987 generation) shared the M97 platform with the Cayman S and uses a compatible pump in most years. Call (240) 301-0095 with your exact year, model, and engine code to verify before ordering.
