20363745 Pressure Pipe | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta position-specific high-pressure fuel pipe used in the injector, pressure-pipe and leak-off-line assembly on THD102KB and THD102KD engines. It is one of the individually formed pipes connecting the mechanical injection pump to the injectors and must be installed in its original schematic position.

🚤 Compatibility

Typically suits:

• Volvo Penta THD102KB
• Volvo Penta THD102KD
• Volvo Penta THD102K-KB

• Engine Family: THD

⚙️ Key Features

• Factory-formed seamless steel injection pipe
• Designed for repeated high-pressure diesel injection pulses
• Correct union cones, thread form and pipe routing for the THD102 installation
• Used with the original attaching clamps and support brackets
• Must not be bent, welded, brazed or substituted with ordinary fuel tubing
• Engine type: Volvo Penta 10-litre six-cylinder mechanical-injection diesel

🔌 Function

Carries a high-pressure injection pulse from the fuel-injection pump to its assigned injector without pressure loss or timing distortion.

⚠️ Common Signs of Failure

• Diesel mist or wetness around a union
• Cracked pipe caused by missing or loose support clamps
• Cylinder misfire or reduced power
• Damaged sealing cone or cross-threaded union
• Fuel spray or pulsing leakage while the engine is running

🛠️ Service Notes

• Cap or plug both ends and keep the pipe and its unions scrupulously clean until the moment it goes on — a pressure line is no place for grit
• Offer the pipe up unstressed: start both unions by hand and let the pipe find its own line before anything is tightened down
• Never bend, straighten or reshape a pressure pipe to make it fit, and never dress or file a sealing cone; a pipe with a damaged or distorted seat is scrap
• Tighten the unions to the figures and sequence in the workshop manual for your engine, and renew rather than refit any pipe the manual treats as a single-use part
• Refit every clip and support bracket so vibration is not carried on the unions, then run up and check for weeps at working pressure, keeping hands well clear of any high-pressure fuel joint
