Checked tanksinc.com they seem to have the items my issue now is finding someone who has been down this road and will share some knowledge on doing this on a 3100 trk. My cross member I put in for the coil overs on the 4 link rear has left me with an opening of 14-15 inches. I need 17 3/4 in for the tank plus some room for attaching the tank. Does moving the rear cross member cause any major issues?? Any hot tips on line configuration or which regulators and pumps to use etc?? Would just like to avoid any mistakes from someone who has done this. Engine is LS1 5.3 from a 05 Tahoe stock non modified. Thanks for any help!
