I know this isn't the answer you are looking for. I used the OEM fuel pump in my Gen 3 installation. Since I have a PU I simply mounted an 04 Dakota tank in the bed of my truck and installed the fuel pump from the 03 RAM that donated the Hemi. However, this may be a viable option for your installation.
