I did a search didnt come up with anything.

Heres what I wanted to know.

When turboing a rsx or ep if I remember right they have returnless systems.

How do they go about that. What setup do they do to keep the fuel up even under boost?

add a fuel return

 

I was reading online about a "feed controlled by a pressure demand regulator, plus new fuel injectors with higher maximum flow rates" to alow the system to not go lean
