11431604 Fuel Pipe | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta preformed rigid fuel pipe used in the low-pressure fuel supply and filter circuit of the TAD1650VE industrial diesel engine. It carries fuel between the filter-housing circuit and the adjoining fuel-system connection while maintaining the correct routing, bend profile and connection alignment required around the engine.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD1650VE

• Engine Family: TAD
• Year Range: Approximately late 2000s-late 2010s; final fitment is controlled by the engine specification number

⚙️ Key Features

• Genuine Volvo Penta OEM rigid fuel pipe
• Correct Volvo Penta part number 11431604
• Preformed specifically for the TAD1650VE fuel-system layout
• Maintains correct clearance and alignment around adjacent components
• Used with the specified hollow screw, sealing gasket and fuel-system fittings
• Engine type: Volvo Penta 16.1L inline 6-cylinder electronically managed industrial diesel

🔌 Function

The pipe transfers diesel fuel through the low-pressure supply and filtration circuit while maintaining the factory routing and connection geometry. Its rigid preformed shape prevents hose collapse and keeps the fuel line clear of hot, moving and vibrating engine components.

⚠️ Common Signs of Failure

• Visible fuel weeping or staining at the pipe ends or along its length
• Loss of fuel pressure, hard starting or rough running caused by a leak or restriction
• Cracking, chafing or corrosion of the pipe body from vibration or contact wear
• Damaged or distorted sealing faces and threads that will not seal after retightening
• Fuel odour or air drawn into the system leading to repeated bleeding

🛠️ 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
