Fuel Pumps
- Porsche 911 1978-1983 3.0L / SC
- Porsche 911 1978-1989 3.3L Turbo (930)
Fuel pump and fuel sender kit for Porsche 911 3.0L SC 1978-83 / 3.3L Turbo (930) , 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 911 3.0L SC 1978-83 / 3.3L Turbo (930)
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 911 3.0L SC 1978-83 / 3.3L Turbo (930) 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.

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.

* 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.

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.
Genuine Porsche Fuel Pumps
Factory-original pumps designed to deliver exact pressure
and flow rates as specified by Porsche for peak efficiency and performance.
Aftermarket Fuel Pump Replacements
High-quality, cost-effective alternatives that match or
exceed OEM standards - ideal for both maintenance and performance upgrades.
In-Tank Fuel Pumps
Submersible pumps mounted within the tank, ensuring constant
fuel supply and quiet, efficient operation.
High-Pressure Fuel Pumps (HPFP)
