Product Information
The Fuel Overflow Hose (commonly known as a fuel return line or leak-off pipe) is an essential component of the Common Rail diesel fuel system. It securely collects excess diesel fuel that is not injected into the combustion chamber and safely routes it back to the fuel tank or injection pump . This high-quality BOSCH hose prevents hazardous fuel leaks, maintains optimal system pressure, and ensures air does not enter the fuel circuit . Engineered with durable, fuel-resistant materials to withstand engine bay heat and vibration, it serves as an exact OE replacement for various Alfa Romeo, Fiat, and Lancia models .
About the Manufacturer: BOSCH is a pioneering global leader in automotive technology and diesel fuel injection systems. As an Original Equipment Manufacturer (OEM), BOSCH provides components engineered with premium materials to resist heat, pressure, and chemical degradation, guaranteeing a perfect fit and long-lasting durability .
- ✔ Genuine BOSCH OEM engineering ensures a perfect, leak-free connection with fuel injectors and return ports .
- ✔ Manufactured from high-grade, diesel-resistant materials to prevent cracking, hardening, and fuel weeping .
- ✔ Exact replacement for OEM part numbers including Fiat/Alfa Romeo/Lancia 46802837 and 55209929 .
- Visible diesel fuel puddles or weeping around the injectors and top of the engine block.
- Strong, persistent smell of diesel fuel inside or outside the vehicle.
- Hard starting or prolonged cranking caused by air entering the fuel system through cracked lines.
- Reduced fuel economy and potential engine hesitation.

⚠ Diagnostic & Installation Tip ⚠
Before replacing the fuel overflow hose:
- Always ensure the engine is fully cooled down and depressurize the fuel system prior to removing any lines to prevent injury and fire hazards .
- Carefully clean the area around the injector return ports before installation to prevent any debris from compromising the new O-ring seals, which could lead to immediate leaks .
- Be extremely gentle when pressing the plastic connectors onto the injectors. Applying excessive force or installing them at an angle can snap the fragile plastic nipples .
