# 3886062 Volvo Penta Fuel Rail | Genuine Used Part

🔧 Product Description

  

Genuine Used Volvo Penta D4 Common-Rail Fuel Manifold - Part Number: 3886062

  

A genuine pre-owned Volvo Penta high-pressure common-rail fuel manifold for selected D4 marine diesel engines.

  

The rail receives pressurised diesel fuel from the high-pressure pump, stores it at a controlled pressure and distributes it to the individual injectors through rigid high-pressure lines.

  

This is a precision high-pressure diesel component. Correct engine identification, internal cleanliness and sealing are essential.

🚤 Compatibility

  

Commonly used on:

  

• Volvo Penta D4 common-rail marine diesel engines

• Inboard propulsion systems

• Aquamatic sterndrive installations

• Early-generation electronically controlled D4 fuel systems

  

Verified example applications include:

Important fitment note:

  

• Confirm the full engine designation, product number and serial number.

• Volvo Penta D4 and D6 engines use multiple fuel rails that are not automatically interchangeable.

• High-pressure pipe positions, pressure valves and sensor arrangements must match the original system.

• Injectors, pressure sensor, control valve and high-pressure lines are included only when shown or described.

  

🔌 Function

  

The rail dampens pressure fluctuations from the high-pressure pump and supplies each injector with fuel at a stable commanded pressure.

  

Common signs of rail or related-system problems:

  

• Difficult starting

• Engine cranks without starting

• Rail-pressure fault codes

• Reduced-power or limp mode

• Fuel pressure rises too slowly

• Engine stalls under load

• Diesel fuel leaks from a pipe connection

• Pressure-control valve does not regulate correctly

• Internal contamination from pump wear

• Metal debris is found in the fuel system

  

Recommended checks before installation:

  

• Keep every fuel port sealed until installation

• Inspect the rail for rust, water or metal contamination

• Confirm the pressure valve and sensor arrangement

• Replace all specified high-pressure pipe seals

• Never bend or reshape rigid injector pipes

• Check the high-pressure pump for internal wear

• Flush the low-pressure fuel system

• Use clean diesel-service tools and procedures

• Perform Volvo diagnostic rail-pressure testing after installation

• Check carefully for leaks without placing hands near a pressurised diesel spray

  

📦 Condition

  

• Genuine Volvo Penta used part

• Pre-owned high-pressure diesel component

• Cosmetic marks and fuel residue may be present

• Internal cleanliness and pressure integrity must be verified before installation

• Supplied components are limited to those shown or described

• Supplied in protective or equivalent packaging
