    so im at the point where im gunna need to build up my fuel system...
    Its a 6.4 hemi with a cam in a 70 duster

    i like the idea of a return system... i was thinking for now, run a regulator up close to the engine, with a small amount on fuel line in dead head only to fuel rails (for now)... i want to change fuel rails later, so fuel can circulate threw them with regulator... (after its running and on road)

    My question is what is a good fuel pump setup? I was looking at this

    Aeromotive Gen II Stealth Fuel Tanks 18444

    What yall think??
    Thanx

        That's the fuel pump system I'm running on my 6.4, with the regulator mounted on the fire wall in the return line.

        I've lead you along I fear. I have the pump, etc. in my Dart. But, I haven't started the car yet, I'm a couple of weeks away. But I do have the same pump and regulator on my race car (picture attached) and it is very quiet and fuel pressure is easy to set.

          I'm running a brand X LS regulator/filter. It has a built in return. I mounted it close to the tank with a short return line. $30 or so at Autozone. Tanks has a great line of pumps and tanks for the swap.

            I used the GM style filter that has a return port to tank. Tank is a Holley sniper. Works great and the filter is inexpensive. Put it above my axle.

            I used the aeromotive stealth system and mounted the regulator on the firewall to make it easy to set the fuel pressure, you can see it in the picture
