Fuel Pumps
By OE Match
- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
- Porsche 911 1975-1977 3.0L Turbo (930)
Fuel pump and fuel sender kit for Porsche 1974-1977 2.7L / 1976-77 3.0 Carrera / 930 1975-1977 3.0L Turbo, combines key fuel delivery and level-sensing components in one package.
What This Product Does
This kit brings together a replacement fuel pump and sender unit to deliver fuel from the tank at the correct pressure while providing a matching level signal to the gauge. It is intended to support reliable running, consistent fuel supply, and accurate tank level indication on Porsche 1974-1977 2.7L / 1976-77 3.0 Carrera / 930 1975-1977 3.0L Turbo
Functions
- Draws fuel from the tank and feeds it towards the engine
- Helps maintain appropriate fuel pressure within the system envelope
- Measures fuel level within the tank for the dashboard gauge
- Supports smooth starting and running by stabilising fuel delivery
- Assists in preventing fuel starvation when the tank level is low
Symptoms of Fault
- Long cranking, intermittent no-start or cutting out under load
- Hesitation, surging or loss of power at higher revs
- Whining or humming noises from the pump area
- Fuel gauge reading erratically, stuck full/empty or inconsistent with actual level
- Hot-start issues or stalling at junctions
Why Replacement Matters
Age, fuel contamination and electrical wear can cause a pump to become noisy or weak, and sender units can suffer from worn tracks or sticking floats. Replacing tired components helps restore stable fuel flow and more predictable gauge readings, which is particularly relevant on older Porsche 1974-1977 2.7L / 1976-77 3.0 Carrera / 930 1975-1977 3.0L Turbo where many original parts are still in service. Addressing pump and sender issues together can reduce repeat visits into the tank area and supports methodical maintenance on classic 911s.

- Porsche 930 1975-1977 3.0L Turbo
FAQs
- Q: Can a weak fuel pump still allow the car to run?
A: Yes, a tired pump may run the engine at light load but struggle to maintain pressure during hard acceleration or higher revs, showing up as hesitation or cutting out. - Q: Do fuel pump problems always trigger obvious noise?
A: Not always, but increasing whining or humming from the tank area is a common early sign, especially if performance has started to deteriorate. - Q: Could a relay or wiring fault mimic pump failure?
A: Yes, low voltage, poor earths or a failing relay can cause similar no-start or intermittent running symptoms, so basic electrical checks are sensible before condemning the pump. - Q: Why does low fuel level sometimes make symptoms worse?
A: With little fuel in the tank, the pump can run hotter and may ingest more debris or air, which makes any underlying weakness more noticeable. - Q: Should the fuel filter be checked when replacing a pump?
A: It is common practice to inspect or renew the fuel filter at the same time, as restriction can overload a new pump and affect pressure.

The red fuel pump relay is an replacement designed to control and protect the fuel pump circuit on classic Porsche 911 models from 1975–89. Built to the same electrical specifications as the original red relay (previously 91161510801), it ensures reliable activation of the fuel pump, stabilises current delivery, and prevents pump operation under unsafe conditions.
Fits:
Porsche 911 1975 - 1989
Porsche 911 Turbo 3.0/3.3L 1975 - 1989
* Please check and match the part number of your relay in your car before ordering.
This red fuel pump relay:
• Controls power supply to the fuel pump, ensuring it only runs when the engine is operating or cranking
• Provides essential electrical protection by preventing voltage spikes and reducing load on ignition components
• Ensures stable fuel delivery for smooth starting, reliable idle and consistent engine operation
• Replaces weak, intermittent or failed original relays that can cause no-start symptoms, stalling or fuel-pressure loss.
A failing red fuel pump relay can cause:
• Intermittent or complete no-start conditions
• Engine stalling, especially when warm Loss of fuel pressure leading to hesitation or uneven running
• Electrical overheating or relay chatter Fuel pump running continuously - a significant safety risk
Replacing the relay restores reliable fuel delivery and ensures the fuel pump operates exactly as Porsche intended.

OE Match electric fuel pump made to the original Porsche specification, featuring a built-in 1-way (check) valve to help retain fuel pressure after shutdown. It supplies fuel at the correct pressure and volume to meet engine demand, helping maintain smooth idle, reliable starting, and strong throttle response.
Fits:
Porsche 911 3.0L Carrera 1976 - 1977
Porsche 924 2.0L 1977 - 1980
Porsche 928 4.5L 1978 - 1980

This part number is commonly listed as superseding 91160810200 and cross-references Bosch 0580254984 (reference numbers for comparison).
This OE Match fuel pump is designed to deliver a steady, pressurised fuel supply from the tank to the engine’s injection system, supporting stable combustion and consistent performance. Manufactured to match the factory form and function, it’s built to the correct flow/pressure characteristics and includes a one-way valve to reduce hot-start issues and improve pressure retention in the fuel lines.
The pump draws fuel from the tank and sends it forward under controlled pressure to the engine’s fuel delivery system. The integrated check valve helps keep fuel from draining back, supporting faster restarts and more stable system pressure.
A weak or failing fuel pump can cause hard starting, hesitation, poor acceleration, lean running, or intermittent cut-out. Replacing it with an OE Match pump restores correct fuel pressure and consistent delivery - critical for performance and engine protection.
When to replace:
• Extended cranking / hard starting, especially hot starts
• Whining/noisy pump or inconsistent fuel delivery
• Hesitation or loss of power under load
• Fuel pressure tests show low or unstable pressure
• During fuel system refresh on higher-mileage cars

OEMatch Fuel Pumps — Fit, Function, Confidence
OEMatch fuel pumps for Porsche models are selected to support application-specific needs and to provide reliable fuel delivery across a wide range of engines. The range covers tank-mounted units, high-pressure pumps for turbocharged engines, and period-correct mechanical pumps for classic models.
Understanding OEMatch Fuel Pumps
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original fuel pumps. OE (Original Equipment) refers to parts matching original specifications for the fuel pumps and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM fuel pumps engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
A fuel pump draws fuel from the tank and delivers it to the engine at the pressures required by the fuel system. Modern Porsche vehicles often use electronically controlled in-tank pumps and separate high-pressure units on forced-induction engines, while older cars may use mechanical pumps. Correct pressure and steady flow are important for combustion consistency and throttle response.
Benefits Include
- Consistent fuel pressure for stable combustion and predictable throttle response.
- Compatibility with factory mounting, connectors and sensors to simplify installation.
- Options suitable for classic restorations, routine maintenance and performance upgrades.
Why Fuel Pumps Wear and Fail
- Contaminated or degraded fuel causing internal wear and blockages.
- Overheating or prolonged operation outside the fuel tank leading to premature failure.
- Electrical faults such as relay failure, connector corrosion or wiring damage.
The Importance of Replacing with OEMatch Fuel Pumps
A failing fuel pump can cause stalling, rough running or starting problems and may affect engine longevity if not addressed. Replacing a worn pump restores stable pressure and delivery, helping to maintain drivability, reduce the risk of misfires and prevent secondary damage that can arise from intermittent fuel supply.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances.
- Available in tank-mounted, high-pressure and mechanical types to suit the model and application.
- Compatible fittings, relays and housings to support reliable installation.
Support & Advice
Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified. Recheck fasteners after initial mileage.
