# 21179351 Fuel Pipe | Genuine Volvo Penta Part

## 🔧 Product Description

Brand-new genuine Volvo Penta precision-formed fuel pipe used in the TAD13 common-rail system. The pipe's flare seats, wall thickness and routing are designed for the high cyclic pressure generated by the rail and injector circuit.

## ⚙️ Key Features

-   High-pressure common-rail pipe
-   Precision flare seats and controlled internal bore
-   Factory bends prevent contact with adjacent lines
-   Single-use service practice after loosening is recommended
-   Pipe only; rail, injector and clamps are separate
-   Engine type: Volvo Penta 12.8-litre common-rail industrial diesel

## 🔌 Function

Carries high-pressure fuel between the rail and the assigned injector or pump connection without pressure loss.

## ⚠️ Common Signs of Failure

-   Diesel mist or wetness at a flare
-   Rail-pressure fault or hard starting
-   Crack caused by vibration
-   Damaged flare seat after reuse
-   Cylinder imbalance from restricted or leaking fuel delivery

## 🛠️ 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
