It performs the normal fuel-level sensing function while also providing a path for excess fuel to be routed back to the tank.\u003c\/p\u003e\n\n\u003cp\u003eA return line is commonly used with aftermarket EFI systems, high-pressure electric fuel pumps, and bypass-style fuel pressure regulators. In these systems, fuel that is not immediately needed by the engine is returned to the tank. This can help the fuel system maintain the pressure and circulation required by the specific pump, regulator, or EFI configuration.\u003c\/p\u003e\n\n\u003cp\u003eThis unit is generally not necessary for a stock-style Mustang using a carburetor, engine-mounted mechanical fuel pump, and single supply line. Those applications normally use a sending unit without a return provision. Before ordering, verify that your fuel system requires a return line and that its supply line, return line, pump, regulator, and fittings are compatible with this sending unit.\u003c\/p\u003e\n\n\u003cp\u003eDesigned to mount inside the fuel tank, this direct-fit replacement uses a 3\/8 inch fuel outlet and includes the additional return provision required by compatible return-style layouts. It is a strong choice when installing an EFI conversion, adding a bypass regulator, upgrading to an electric fuel pump, replacing the fuel tank, repairing the fuel gauge, or refreshing a previously modified fuel system.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003cp\u003e\u003cstrong\u003eChoose this sending unit when your 1965-1968 Mustang has a return-style fuel system that requires a dedicated line back to the tank.
