Hey guys, Im in the works of building a boosted 5.3 . Going to be running dual pumps. not decided on 255s or 450s yet. But my question is since ill be running a stock ls1 fuel rail, ill order an fpr that has a built in return line. My question is where do i hook that return line up at? is there a place in the hat to connect to? also do i need to pull the factory fpr out of the hat? Cant find a whole lot of info on it.

Thanks

you need to remove the stock unit in the tank

and then what? run a return line from the regulator to the hat? is there a connection there?

Use your Evap line as your return line and just vent the Evap line from the tank to atmosphere

thank you very much for that diagram. i havent ripped into the fuel system yet so i was kinda blind on that one. Thanks for clearing it up for me. For some reason i couldnt find much info on how to do it.
