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.
