Ok i have been working on finishing up my sr20 swap for some time now, i am currently working on running new fuel lines and i have come across somthing i didnt really think about. i know that the rx8 has a returnless fuel system but i have noticed that there is a second line that goes from somwhere under the hood to a charcoal can in the back of the car. my qeustion is do i need to run a fuel line from my sr back to that canister? and also if anyone knows how much pressure our stock pump puts out as well as lph that would be helpful. any input anyone?.

 

The stock pump is similar in output to the regular 190lph pumps out there.

The second system is for the fuel gases system. It actually goes to a solenoid on the intake manifold. You should probably leave this system as is, it doesn't help or deter from what you are trying to accomplish.

ok so i should just cap off the line going to that box and be done
