21086311 Fuel Pipe | Genuine Volvo Penta Part

🔧 Product Description

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.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD550GE
• Volvo Penta TAD551GE
• Volvo Penta TAD734GE
• Volvo Penta TAD750GE
• Volvo Penta TAD751GE
• Volvo Penta TAD752GE
• Volvo Penta TAD753GE
• Volvo Penta TAD754GE

• Engine Family: TAD

⚙️ 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
• Engine type: Electronically controlled inline-six industrial/generator diesel

🔌 Function

Carries low-pressure fuel between the specified pump, filter or engine fuel-gallery connection while maintaining a sealed, mechanically supported flow path.

⚠️ Common Signs of Failure

• Fuel dampness or leakage at the banjo/flare connections
• Air entering the fuel system and causing hard starting
• Cracked pipe near a bend or unsupported section
• Chafing against an adjacent bracket or engine component
• Unstable running or power loss caused by restricted fuel delivery

🛠️ Service Notes

• Work clean: cap or plug every open union and injector as soon as it is disconnected, and fit the new pipe straight from its packaging — dirt introduced at a fuel joint is the most common cause of trouble afterwards
• Offer the pipe up so it lines up on both unions without strain, and never bend, twist or reshape a pipe to make it fit; a pipe that has been sprung into place fatigues and cracks in service
• High-pressure delivery pipes are treated as single-use in workshop practice — the union faces seal by deforming, so refit new pipes rather than reusing them, and tighten to the figure and sequence in the workshop manual for your engine
• Refit all original support clips and brackets in their proper positions so the pipe cannot chafe or vibrate against surrounding parts
• Bleed the system, then check the joints for leaks with the engine running and again once warm — never search for a diesel leak by hand, since fuel at injection pressure will penetrate skin
