Three-Port Original vs Two-Port Upgraded Design Benefits of the Updated Design
Original Fuel Pump (3 Connections)
New Design (Supplied Pump with 2 Connections)
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.
