6.5 TD OPS lift pump power supply

Hi everyone, I have a question about the 6.5 diesel lift pump circuit. According to what I have read, the fuel pump relay is supposed to supply the voltage to run the lift pump and the OPS is supposed to supply the voltage in case the FP relay stops working. So why not eliminate the OPS feed so it does not overheat or ruin the OPS. A light could be mounted in the dash that indicates when the lift pump is being supplied with voltage, and if the relay went bad the light would go out. Any thoughts? Thanks


Al
