Information
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.

Information
Fuel pump relay.
This relay sits between the ignition switch / DME and the fuel pump electrical circuit — its role is to switch the 12 V supply to the pump when the engine is running (or ignition is on), ensuring consistent and reliable fuel delivery. Activation of this relay is essential for proper fuel-pump operation and stable fuel pressure throughout the engine’s runtime.
Fits:
Porsche 924 1976 - 1978
* Please check and match the part number of your relay in your car before ordering.
A fuel-pump relay can degrade over time due to heat, vibration and internal electrical wear. When the relay begins to fail, the fuel pump may not receive power consistently, leading to hard starting, stalling or complete no-start conditions. Replacing an aging or faulty relay ensures stable fuel delivery, protects the wiring system and maintains reliable engine performance.
Reasons to Replace:
• Fuel pump does not activate even though the engine cranks
• Intermittent fuel pump operation or unstable fuel pressure
• Relay becomes hot, buzzes or produces electrical smell
• During wiring repair, harness work or full vehicle restoration
• The relay is decades old and may fail without warning (preventative maintenance).
