Mechanical Pump with Return Line- input/pictures/etc.

I have my new tank installed with 3/8" lines run for feed and return Sending unit with additional nipple for return.) For now I will be keeping the Mechanical Pump with Carb and if someone else has done this please chime in with where you sent fuel back to the tank in reference to how far past the Fuel Pump on the feed line. I am running a Carter Pump and will not be needing a Regulator. No Electric Pump also. Pictures would be great also.

I looked through the search and only found Electric Pump setups. But I am not known for being savvy on the net at times lol....

Thanks,
JW
