24155787 Rail | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta fuel rail from the Fuel System group, weighing 1.168 kg. Four rails are listed together in this block: 24155788 is published at 1.132 kg, while 24155789 and 24155790 carry no published weight at all. The 36 grams between the two figures that do exist prove nothing about which rail suits your engine, so order by part number against the engine's own identification.

⚙️ Key Features

• 1.168 kg
• Fuel System group
• One of four rails listed together with 24155788, 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

• Diesel weeping or a strong fuel smell around the rail and its unions
• Hard starting or a rough idle from a rail that will not hold pressure
• Rail pressure faults or power derate warnings logged by the engine
• Corrosion or damage at a sensor seat or relief valve seat
• Fretting or bright rub marks where a high pressure pipe union has worked loose

🛠️ Service Notes

• A high pressure fuel system holds dangerous pressure after shutdown - let it depressurise fully before slackening any union, as an escaping jet can pierce skin
• Renew the high pressure pipes rather than reusing them; their ends bed into their seats and rarely seal a second time
• Cap the rail and every open union while the rail is off the engine, because debris that enters a rail ends up in the injectors
