Information
Injection pump belt
This OE Match injection pump belt is a replacement drive belt for the mechanical fuel injection system on Porsche 911 models from 1969 to 1977. It is designed to match the original-style fitment and function. This replacement belt helps drive the mechanical fuel injection pump, supporting correct fuel delivery and reliable engine running.
Fits:
Porsche 911 1969 - 1977
Diagram ref no 21
The injection pump belt transfers rotational drive to the fuel injection pump. This allows the pump to operate in sync with the engine and deliver fuel correctly. A good belt is essential for accurate fuel delivery, smooth running, and dependable engine performance on models using mechanical fuel injection.
Functions
• Replaces the injection pump drive belt
• Drives the mechanical fuel injection pump
• Supports correct fuel delivery and engine running
• Helps maintain injection pump timing and operation
• Replaces cracked, worn, stretched, frayed, or missing belts
• Suitable for fuel injection system service and preventative maintenance
• OE Match replacement for classic Porsche 911 engine service.
Why Replace This Part?
Injection pump belts wear over time due to heat, age, tension changes, pulley contact, vibration, and engine bay conditions. A worn belt can crack, stretch, fray, slip, or fail completely. If the belt fails, the injection pump may stop operating correctly, causing poor running, loss of fuel delivery, difficult starting, or engine stoppage. Replacing the belt helps maintain reliable mechanical fuel injection performance.
When to Replace This Part
• The injection pump belt is cracked, glazed, frayed, loose, or worn
• Fuel injection pump service or adjustment is being carried out
• Engine running is poor due to suspected injection pump drive issues
• The belt tension is incorrect or unstable
• The injection pump, pulleys, or related components are being serviced
• Preventative belt replacement is being carried out during scheduled maintenance
• The vehicle is undergoing Porsche 911 fuel injection or engine restoration.
Where it fits on the car
This belt fits within the mechanical fuel injection pump drive system on Porsche 911 models from 1969 to 1977. It runs around the relevant injection pump drive pulleys according to the factory engine layout.
