    i just installed my JR fuel pump so i could get it done before the SC install,can this harm the motor,and will it be too rich ?
    i drove it afterwards, and it drove like a bat out of hell, pulling hard as sh!t.my only concern is that can it hurt my o2 sensor ? or the motor ? By the way, it seemed to pull harder than before the pump, maybe its because my Type R cams up top. thanks for any info.

    you have nothing to worry about other than extra fuel circulation. The fpr returns any extra un-needed fuel back to the tank.

    The only way you would be getting more fuel is if your original pump had a problem.

    I put my fuel pump in a week before the SC and had no problems.

    Good luck with the install.

    Same here, I put mine in about a month b4. It is just nice to get things out of the way b4 the install if you can.
