- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
This Fuel Pump is an OE Match high-pressure mechanical fuel injection (MFI) pump designed for classic Porsche 911 models. It delivers fuel from the tank to the engine-driven MFI system.
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
- 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.

Fits:
Porsche 911 1974 - 1989
Porsche 911 Turbo 1975 - 1989

This rubber mount cushions the fuel pump, reducing vibration and noise while helping keep the pump securely in place during operation. It also protects adjacent components from mechanical stress caused by engine vibration and motion.
Over time, rubber buffers can harden, crack, or deteriorate from heat and age, leading to excessive vibration, noise, and potential stress on the fuel pump assembly. Replacing worn mounts with OE-match buffers ensures the fuel pump remains secure and smooth-running, preserving the integrity and reliability of the fuel delivery system.
When to replace:
• Rubber buffer shows cracks, splits, or hardening
• Noticeable vibration or noise from the fuel pump area
• Fuel pump feels loose or poorly supported
• During fuel system servicing or restoration
• As part of routine preventive maintenance
