I'm pretty sure that the item in Red is the secondary(high pressure fuel pump). To avoid vapor lock, there is a low pressure pump on the engine which feeds the high pressure electric pump. One line on the pump is from the low pressure pump, the other goes directly out to the injectors, and the third is the pressure relief that feeds back to the tank so the pump doesn't deadhead.
