Displayed here is a
diagram of how the fuel
lines are routed when run-
ning a return setup with
your fuel pressure regula-
tor. From the diagram you
can see that the fuel pres-
sure is regulated after the
fuel rail meaning that fuel
must be able to flow in
and out of the fuel rail. If
you want to run a tucked
fuel line setup, this config-
uration will not work.
