For those of you who have installed a bigger intake and Supercharger or swapped fuel rails, are you still running a line from the damper to the coupler? Can it just be capped if I install a boost-a-pump?

That is not a pulse damper, it is your fuel pressure regulator just cap it and it will maintain your FP @60psi all the time if you have enough pump. Or you can run a line to it from your intake and have it tuned that way but your tuner will not like you.......

Thanks for the info. ECS will be my tuner next week.
Now I need to find out if it's worth it to change to a single fuel line system.
