Fuel supply is the one that brings the fuel to fuel rail, Fuel return is just that it returns unused fuel to the fuel tank and the vapor line is for emission and returns fuel vapor to the gas tank through the vapor canister

The fuel pump will still not hold pressure it is built into the pump the only way to fix it is to replace the pump. So even if you put a check valve inline it will still leak down at the pump if that's the only way you can fix it then as close to the tank as possable
