22338633 Pipe | Genuine Volvo Penta Part

🔧 Product Description

A genuine rigid high-pressure supply pipe used between the fuel pump and common rail on the Volvo Penta D8A1-A MP. The pipe is formed for the original pump and rail positions and must seal at full common-rail pressure without side loading the unions.

🚤 Compatibility

Typically suits:

• Volvo Penta D8A2-A MP
• Volvo Penta D8A1-A MP

• Engine Family: D

⚙️ Key Features

• Genuine Volvo Penta common-rail supply pipe
• Connects the high-pressure pump and common rail
• Catalogued for D8A1-A MP
• Precision formed for the original pump and rail locations
• High-pressure sealing cones and union geometry
• Critical clean fuel-system component; replace if damaged

🔌 Function

Transfers fuel from the engine-driven high-pressure pump to the common rail for storage and distribution to the injectors.

⚠️ Common Signs of Failure

• Rail pressure too low or slow pressure build
• Fuel leakage at the pump or rail union
• Hard starting or engine shutdown
• High-pressure fuel fault codes
• Fatigue cracking or rubbing damage
• Damaged sealing cone from misalignment

🛠️ Service Notes

• Offer the pipe up and check it reaches both connections freely before you tighten anything — a rigid pipe pulled into place is a pipe left under permanent strain, and strained pipes crack at the fittings in service
• Renew the sealing washers, O-rings or union seals that go with the pipe rather than reusing the old ones, and make sure the seats, faces and threads are clean
• Keep the ends capped while you work and blow or flush a pipe through before fitting; anything left inside goes straight into the oil, fuel or coolant system
• Tighten unions and banjo bolts evenly to the figures in the workshop manual for your engine — overtightening distorts the seat and starts the leak you were trying to cure
• Refit every clip and support bracket in its original place and keep the pipe clear of hot or moving parts so it cannot chafe or be shaken to failure
