Anyone ever install a fuel cell in their Rx8? After a little research i discovered the rx8 does not have one just a damper.Did you install a adjustable fuel pressure regulator? If yes how did you hook it up and did you use one with a return?

 

Stock Fuel system is a returnless system. The regulator is built in to the fuel pump assembly and it runs a constant pressure up the fuel rail to the injectors.

You can install a fuel cell and a return line to run a normal return type system...or you can run a regulator that feeds the system like stock...and returns the extra at the fuel cell like the stock system

There are pros and cons to both...so you need to decide what you want to do and go from there

 

Appreciate the info but there seems to be two lines running to the tank one is the feed the other I though was a return from the Fuel Damper. I was thinking of two options and would appreciate any comments.
Option 1
I was planing to put a Fuel Regulator and plug the the return and use the return from the damper. (if that is the return from the damper)
Option 2
Use the return on the regulator and T into the questionable return from the fuel damper.

 

Looking to set fuel regulator can someone inform me of the required pressure

 

One line is the fuel tank vent line and one is the fuel feed line, neither is a return line for fuel
