Efi return pressure?

Currently installing a pro-flo efi and remote sump. I'm using the abandoned factory vent line for my return. I'm also thinking I can T into that line with the remote sump vent line. Does anyone know what the pressure is on a typical efi return line? I'm hoping it doesn't back feed return fuel into the sump. If so, I guess I'll add a check valve.
Thanks
