I run a stock in cab tank with my fitech and I have used both in line (frame Mount) and In tank fuel pumps , I used a old in tank fuel pump I had laying around to see if it would work I attached it to the pick up tube. It was definitly very quiet ,but I did have slosh issues below a 1/4 tank , the external frame mount pump does make a lot of noise but works well , as far as return line fitech sells a bulk head fitting that easly is put in to any tank for the return line , I also used 72 style sending unit because it has a vent and you need to properly vent this tank when routing a return lin back in to it. in the picture the return bulk head fitting supplied by fitech is to the left , I also recoment that your pump feed line after the pump weather you go in tank or frame rail pump is done in hard line not efi hose . I hate the noise and will return to the intank pump when I get a chance to figure out the the slosh issues.
