21086311 Fuel Pipe | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Fuel Pipe - Part Number: 21086311

A genuine Volvo Penta rigid fuel pipe used in the TAD734GE fuel-supply system around the engine-mounted fuel pump and filter connections. The pipe is manufactured with the correct flare or banjo interfaces, bend geometry and mounting position so it seals without being pulled into alignment. Reusing a distorted pipe or forcing a substitute line into place can introduce air, cause fuel leakage or fatigue the connection.

⚙️ Key Features

• Engine-specific formed steel fuel line for the TAD734GE fuel system

• Correct bend geometry maintains clearance from hot and vibrating components

• Precision sealing ends suit the original hollow-screw and gasket arrangement

• Rigid construction maintains stable fuel flow without hose expansion

• Fuel-system cleanliness and correct support are mandatory during installation
