Product 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).

About Fuel Pumps

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.
