This genuine Porsche oil line (part number 901-110-041-03) is a critical component of the Bosch mechanical fuel injection (MFI) system used on classic Porsche 911 models. The line supplies engine oil to lubricate the internal mechanicals of the MFI pump, which is essential for proper operation of this high-performance fuel delivery system.

Key Features:

• OEM Porsche quality ensures proper fit and function
• Designed specifically for Bosch mechanical fuel injection pumps
• Critical for maintaining proper MFI pump lubrication
• Precision-engineered metal construction for durability
• Direct replacement for worn or leaking original lines

The Bosch mechanical fuel injection system was used on high-performance 911 models and requires two oil lines—one for supply and one for return—to keep the pump's internal camshaft, pistons, and galleries properly lubricated. Regular inspection of these oil lines is essential, as leaks can lead to pump failure and potential fuel contamination of engine oil. This genuine Porsche replacement line maintains the exacting tolerances required for reliable MFI system operation.
