Fuel pump relay red.
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.

About Relays / Fuses

Relays & Fuses – Reliable Electrical Protection for Porsche Vehicles

Relays and fuses are vital components of your Porsche’s electrical system, responsible for controlling power distribution and safeguarding critical circuits. Relays act as electronic switches that manage high-current loads efficiently, while fuses protect your electrical components by breaking the circuit during power surges or faults.

At Design911, we stock an extensive range of genuine and high-quality relays and fuses suitable for all Porsche models, including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each part is precision-engineered for compatibility, durability, and performance, ensuring your Porsche’s electrical system functions safely and efficiently.

What Do Relays and Fuses Do?

These small but essential components perform critical roles in your vehicle’s electrical and safety systems:

  • Relays: Act as electrical switches that control power to key components like the cooling fan, fuel pump, headlights, and ignition system.
  • Fuses: Protect circuits by preventing overloads or short circuits, ensuring safe operation of electrical systems.
  • Together: They maintain stable power distribution and prevent damage to sensitive electronics.

Proper relay and fuse function is essential to keeping your Porsche’s complex electrical systems running reliably under all driving conditions.

Why Do Relays and Fuses Fail?

Over time, relays and fuses can degrade due to heat, vibration, or electrical stress. Common causes of failure include:

  • Corrosion or oxidation on terminals.
  • Overheating caused by excessive current draw.
  • Electrical arcing within relay contacts.
  • Fuse fatigue from repeated current surges.
  • Moisture or contamination affecting performance.

When a relay or fuse fails, systems such as your fuel pump, headlights, air conditioning, or ignition may stop working altogether — leading to performance issues or complete electrical failure.

Why Replace Faulty Relays and Fuses?

A failed relay or blown fuse can cause major system malfunctions or even damage other components. Replacing them with manufacturer-quality parts ensures consistent voltage flow, electrical safety, and reliable system operation.

Benefits of replacement include:

  • Restored functionality to critical electrical systems.
  • Protection against short circuits and overloads.
  • Reduced risk of electrical damage and fire hazards.
  • Long-lasting, dependable performance.

All our relays and fuses are designed using heat-resistant materials and precision contacts, ensuring optimal conductivity, quick response times, and extended service life.
