Injection pump belt
The Genuine Porsche 99919203040 injection pump belt is an OE toothed drive belt for the mechanical fuel injection pump on selected Porsche 911 1969–1977 models.

Porsche 911 1969 - 1977
Diagram ref no 21
This belt is used on Porsche 911 models equipped with a mechanical fuel injection system, where it drives the injection pump from the engine drive system.
What This Part Does / Functions
• Drives the mechanical fuel injection pump
• Helps maintain correct injection pump timing
• Supports consistent fuel delivery to the engine
• Helps ensure smooth engine running and throttle response
• Transfers rotational drive accurately through the toothed belt profile
• Helps prevent injection timing issues caused by belt wear or slip
• Provides OE Porsche fitment for the original MFI pump drive system
• Replaces an aged, cracked, stretched or worn injection pump belt.
Why Replace This Part?
The injection pump belt is a critical service item on mechanical fuel injection engines. Over time, the belt can age, crack, stretch, wear or lose tooth definition. If the belt slips, wears excessively or fails, the injection pump may lose correct timing, which can cause poor running, misfiring, difficult starting or incorrect fuel delivery. Replacing it with a Genuine Porsche OE injection pump belt helps maintain accurate MFI pump operation and supports the original performance and drivability of the classic Porsche 911 engine.
When to Replace This Part
• During scheduled mechanical fuel injection system service
• If the belt is cracked, worn, frayed or visibly aged
• If injection pump timing is being reset or adjusted
• During engine rebuild, MFI pump service or fuel system restoration
• If the belt has been contaminated by oil, fuel or debris
• If the belt age or service history is unknown
• When recommissioning a stored classic Porsche 911
• When restoring the engine with correct OE Porsche service parts.
Where It Fits on the Car
This belt fits on the engine mechanical fuel injection system, driving the mechanical injection pump. It is installed in the MFI pump drive area and works with the injection pump pulley system to maintain correct pump timing.
