fuel pump replacement

You have one fuel pump, that is it. It is in the valley of the motor.
It is a two stage mechanical pump between the fuel filter housing and the turbo.
It "brings the fuel from the tank" (pre stage 1) through stage 1, then gets filtered at low pressure. Then it returns to the fuel pump where the pressure is increased through stage 2, then it goes through the banjo bolt on the back of the pump, through the wishbone fuel lines to the back of the heads. The excess fuel comes out the front of the heads, through the flexible fuel lines to the regulator mounted on the fuel filter housing. This regulator restricts stage two pressure to somewhere around 50-60 psi. The excess fuel then returns to the tank.
...Unless, of course, You or a previous owner has already converted to electric.
