22338630 Pipe | Genuine Volvo Penta Part

🔧 Product Description

A genuine common-rail injector pipe serving cylinder 4 on the Volvo Penta D8A1-A MP. The factory bend pattern places the pipe between the rail and injector without preload and preserves the high-pressure sealing geometry.

🚤 Compatibility

Typically suits:

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

• Engine Family: D

⚙️ Key Features

• Genuine Volvo Penta high-pressure fuel pipe
• Cylinder position: No. 4
• Catalogued for D8A1-A MP
• Original bend pattern and connection length
• Precision high-pressure sealing ends
• Replace if a union, cone or pipe wall is damaged

🔌 Function

Transfers high-pressure fuel from the common rail to the cylinder 4 injector.

⚠️ Common Signs of Failure

• Fuel seepage or spray at a union
• Cylinder 4 misfire or imbalance
• Pressure decay or rail-pressure fault
• Fatigue crack near a bend
• Damaged sealing cone or thread

🛠️ 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
