When my father back in the 1990s originally did the fuel pump placement to the rear and switch to a 2 port pump, had capped the return fuel line as shown in the photo. There was no connection coming from anywhere back to the return line.

I am in the process of replacing out the fuel pump (again).
So is the return line even needed? Mine could be different because it currently has Weber 40 IDAs on it. Prior to when I had to garage it in 1998 (blown piston ring), it ran for years and years with no return line fuel. So thinking it's a nice to have or mostly for DFI but not required for carbs?
Maybe other Weber owners have a picture of where they are returning fuel from for a hint?
Thanks!
