Fuel flow?

[4g63telantra]

I wanna redo all my furl lines in SS from the tank-to the-fuel rail. What i would like to know is how the FUEL FLOWS. From the fuel pump, where does it flow too? (fuel filter or FPR) and where does it flow back too?

ex. Fuel pump---->fuel filter--->FPR--->fuel rail-->back to tank?

Fuel pump ---> Fuel filter ---> rail inlet (passenger side) ---> FPR (driver's side) ---> Return line ---> Tank

This is how just about all return style systems operate.

The FPR controls the return flow to the tank, which keeps the pressure in the rail adjusted to vacuum/boost. When it wants pressure to rise, it bleeds less fuel back to the tank. When it wants pressure to drop, it allows more flow through.
