Fuel return hose
OE Numbers: LR021871
Vehicle Compatibility: Land Rover
The fuel return line is a pipe responsible for conveying unused excess fuel back to the fuel tank from the engine fuel injection system. Its main functions include maintaining system pressure stability: since the fuel pump delivers fuel at a pressure higher than that required for injection, the return line allows excess pressure and fuel to flow back to the tank, thereby keeping the fuel pressure supplied to the injectors constant; cooling the fuel: by recirculating the fuel through the system back to the tank, it helps dissipate some heat, preventing vapor lock caused by high temperatures in the fuel lines or near the injectors.
Position Connection: One end of the fuel return line is connected to the fuel rail or fuel pressure regulator inside the engine compartment, and the other end is connected to the top of the fuel tank. It corresponds to the fuel supply line that delivers fuel from the fuel tank to the engine, and together they form the fuel circulation loop.
Common Issues and Impacts: If the return fuel line becomes clogged, leaks, or is damaged, it may result in abnormal fuel pressure, which can cause unstable engine operation and increased fuel consumption. In severe cases, there may be safety hazards, such as the smell of gasoline.
