# 21086352 Fuel Pipe | Genuine Volvo Penta Part

## 🔧 Product Description

A genuine Volvo Penta formed fuel pipe used in the TAD734GE engine-mounted fuel-pump circuit. It is a separate line from 21086311 and follows its own defined route within the pump and filter assembly. The original pipe geometry is important for maintaining clearance, avoiding vibration-induced fatigue and allowing the sealing faces to seat without bending load.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta TAD734GE

-   **Engine Family:** TAD

## ⚙️ Key Features

-   Genuine TAD734GE engine fuel-pump pipe
-   Application-specific routing and connection orientation
-   Rigid line prevents expansion and maintains stable fuel delivery
-   Designed to work with the original pump, fittings and sealing washers
-   Must be installed clean and free from internal debris or corrosion
-   Engine type: Electronically controlled inline-six industrial/generator diesel

## 🔌 Function

Transfers fuel through the assigned section of the TAD734GE low-pressure fuel circuit while maintaining a sealed and vibration-resistant connection between components.

## ⚠️ Common Signs of Failure

-   Fuel leakage or wetness at the connections
-   Hard starting after the engine has stood
-   Visible fretting or chafe damage
-   Pipe cracking close to a bend or fitting
-   Fuel restriction caused by internal contamination or deformation

## 🛠️ 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
