Fits:
  • Porsche 911 1969-1973 2.2L / 2.4L / 2.7L RS LWB (F)
Cars with Mechanical Fuel Injection (MFI)

Three-Port Original vs Two-Port Upgraded Design
Original Fuel Pump (3 Connections)

  • Flow in – 10mm Flow to engine-driven MFI pump 
  • 8mm Return from overpressure valve 
  • 8mm back to tank
New Design (Supplied Pump with 2 Connections)
  • Flow in – 10mm
  • Flow out – 8mm
  • Overpressure valve is built into the pump, eliminating the need for a third return port. - A blanking plug is provided to seal the unused return pipe on the vehicle.

Benefits of the Updated Design

  • Simplified installation
  • Fewer potential leak points
  • Internalised pressure regulation
  • Cleaner engine bay layout
  • Modern reliability for classic Porsche fuel systems

The Fuel Pump is designed specifically for classic Porsche 2.2-litre and 2.4-litre Mechanical Fuel Injection (MFI) engines, ensuring reliable, high-pressure fuel delivery essential for Bosch MFI systems. MFI engines rely on precise fuel volume and pressure to maintain accurate metering, throttle response and performance. This upgraded pump meets the demands of the MFI fuel circuit while simplifying the original design for improved reliability and ease of installation.

Engineered to provide consistent fuel pressure, stable flow and long-term durability, this pump is an essential replacement for ageing or failing fuel system components on classic MFI-equipped 911 models.

What This Fuel Pump Does

The fuel pump is responsible for:

  • Delivering high-pressure fuel from the tank to the engine-driven MFI pump
  • Maintaining stable fuel pressure required for accurate MFI metering
  • Ensuring consistent flow under varying throttle loads
  • Reducing fuel system complexity with a built-in overpressure valve
  • Supporting smooth idle, crisp throttle response and clean acceleration

It is an essential component in maintaining proper MFI function and engine performance.

Why Original MFI Fuel Pumps Fail

Mechanical fuel injection systems operate under high pressure and constant fuel circulation. As pumps age, they become prone to:

  • Internal wear reducing pressure and flow
  • Blocked valves or degraded seals causing erratic fuel delivery
  • Corrosion inside the pump housing affecting reliability
  • Electrical motor wear leading to inconsistent operation
  • Overpressure valve problems, especially on original three-port designs
  • Fuel contamination or varnish buildup from ageing petrol

Symptoms include rough idle, poor throttle response, hesitation, loss of power, hard starting or surging under load.

Why Replace with This Modernised Pump

Upgrading to this precision-engineered pump ensures consistent, reliable operation:

  • Stable high-pressure output for MFI accuracy
  • Improved reliability and reduced failure points
  • Simplified plumbing with built-in overpressure management
  • Modern materials for longer service life
  • Direct compatibility with Porsche 2.2L / 2.4L MFI systems
  • Smoother engine operation and improved drivability
  • Ensures proper performance on restored or rebuilt engines

This pump is a direct, practical and reliable solution for keeping classic MFI Porsches running as intended.

About Fuel Pumps

Maintain your Porsche’s performance and reliability with genuine and aftermarket fuel pumps from Design911. Designed to deliver precise fuel pressure and volume, these pumps ensure optimal engine performance, efficiency, and smooth acceleration across all driving conditions.

What They Are & What They Do
A fuel pump’s primary job is to draw fuel from the tank and supply it to the engine at the correct pressure. In modern Porsche vehicles, fuel pumps are electronically controlled to meet precise engine demands, while older models use mechanical or in-tank units for continuous fuel flow.
Proper fuel pressure is vital for efficient combustion, smooth throttle response, and power delivery — especially in high-performance engines.

Why They Fail
Fuel pumps can fail over time due to contaminated fuel, worn internal components, overheating, or electrical faults. Blocked filters, running on low fuel, or poor-quality fuel can also cause pressure loss, irregular delivery, or total pump failure, leading to misfires, engine hesitation, or starting issues.

Why They Should Be Replaced
A failing fuel pump compromises engine performance, fuel economy, and reliability. Replacing it ensures consistent fuel flow, stable pressure, and smoother operation, preventing costly engine damage.
Upgrading to a genuine or high-performance aftermarket fuel pump from Design911 guarantees OEM-quality materials, precise calibration, and long-lasting durability. Whether restoring a classic 911, maintaining a Cayman or Boxster, or tuning a Turbo or GT model, we have the right fuel pump solution for your Porsche.
