⚙️ Key Features

• Genuine Volvo Penta OEM part number 1545081
• System group: Fuel System
• Net weight approximately 0.13 kg
• Fits AQ, BB, MB/MD, TMD, TAMD, TD100, TID100, THD102, TAD1030-series and TWD engine families
• Serves the injector leak-off (fuel return) circuit
• Engine type: Volvo Penta 10-litre mechanical-injection diesel

🔌 Function

The leak-off pipe collects excess fuel that bleeds past the injectors and channels it back into the return line to the fuel system. This maintains correct injection pressure conditions and prevents fuel accumulating around the injector bodies.

⚠️ Common Signs of Failure

• Fuel weeping or dripping at the pipe joints and injector connections
• Cracked, split or hardened pipework after long-term heat exposure
• Strong fuel odour in the engine compartment or fuel in the bilge
• Hard starting, rough running or misfire caused by air drawn into the fuel circuit
• Corroded, distorted or loose connection ends that will no longer seal

🛠️ Service Notes

• This pipe spans both the petrol (AQ, BB, B20) and diesel (TD, TID, THD, TAMD) variants of the 10-litre engine family - a wider span than most leak-off pipes in this range, so confirm your exact engine variant before ordering
• Check the engine's serial number against the parts list break point before ordering, since several pipes in this family are split by a mid-production serial change
• Renew the sealing washers at each union rather than reusing them, and bleed the fuel system fully after fitting
