24155788 Rail | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta fuel rail from the Fuel System group, weighing 1.132 kg. It is listed with 24155787 at 1.168 kg and with 24155789 and 24155790, neither of which carries a published weight. With two of the four unpublished, weight is no guide to which rail belongs on which engine, so order by part number.

⚙️ Key Features

• 1.132 kg
• Fuel System group
• One of four rails listed together with 24155787, 24155789 and 24155790
• Weight does not identify the rail - order by part number

🔌 Function

Holds high pressure fuel from the pump in a common reservoir and feeds each injector from it, damping the pressure pulses between injection events.

⚠️ Common Signs of Failure

• Fuel smell or wet diesel tracking down from a union
• Rough running, misfire or an engine that will not hold rail pressure
• Pressure faults or a derate logged against the fuel system
• Pitting or corrosion at a sensor or valve seat in the rail
• Rub marks or a loosened union where a pipe has been vibrating

🛠️ Service Notes

• Let the high pressure side depressurise before opening any union - the pressure remaining after shutdown is enough to injure
• Fit new high pressure pipes with the rail rather than reusing the old ones
• Keep every port capped while the rail is off, since dirt entering the rail is passed straight to the injectors

📦 Condition
