# 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
