    Early or late model?

    Are you using E46 M3 fpr? How/where is it mounted ? Sure it's good?
    I'm using the stock in tank pump with walbro inline 255. E46 m3 FPR. When the fuel pump was running it had lots of pressure on the FPR bleeder valve.

      Why not use the deatschwerks/walbro/TRE/etc 255lph in tank pump and eliminate the in line pump?

        M3's have the dual pump system I heard I'd have to change my gas tank to run the single pump setup

          I can get the fuel pumps to run if I run a 12v switched jumper to the fuel pump pin on the C101

            It fires right up now and idles! I wired pin 8 on the EKP fuel pump relay right to pin 7 on the c101 (switched 12v). I had it tapped into another switched 12v before and that wasn't good enough I guess.
